Description

レーダ装置及び電波干渉の回避方法Radar apparatus and method for avoiding radio wave interference
　本発明の実施形態は、レーダ装置及び電波干渉の回避方法に関する。 Embodiments described herein relate generally to a radar apparatus and a method for avoiding radio wave interference.
　近年、無線LAN等の無線通信装置は、大容量通信等を目的に使用周波数の高周波化が推進されている。このため、無線通信装置と気象レーダ等のレーダ装置との間で、両者の使用周波数帯域が重なることにより、電波干渉が発生する可能性が高くなっている。 In recent years, wireless communication devices such as wireless LAN have been promoted to increase the frequency of use for the purpose of large-capacity communication. For this reason, there is a high possibility that radio wave interference will occur between the wireless communication device and a radar device such as a weather radar because the frequency bands used by both devices overlap.
　従来では、例えば５ＧＨｚの周波数帯域を使用する無線LANの場合、当該周波数帯域は気象レーダ等のレーダ装置においても使用されているため、電波干渉が発生する可能性がある。このような電波干渉を回避する対策として、例えば、無線LANのアクセスポイントには、一般的にＤＦＳ（Dynamic Frequency Selection:動的周波数選択）と呼ばれる電波干渉の回避機能が搭載されている。 Conventionally, in the case of a wireless LAN using, for example, a frequency band of 5 GHz, the frequency band is also used in a radar apparatus such as a weather radar, so that radio wave interference may occur. As a measure for avoiding such radio wave interference, for example, a wireless LAN access point is equipped with a radio wave interference avoidance function generally called DFS (Dynamic Frequency Selection).

　電波干渉を回避する対策として、例えば、無線LANのアクセスポイントにはＤＦＳ機能が搭載されている。このＤＦＳ機能は、アクセスポイントが受信した信号の中に、予め定義されたレーダ装置のパルスパターンが含まれているか否かを判定する。当該パルスパターンは、パルス幅、パルス繰り返し周波数（パルス繰り返し間隔）、パルス数等のパラメータにより定義されている。ＤＦＳ機能は、当該パルスパターンが含まれていると判定した場合（検知した場合）には、他の周波数のチャネルに変更することで、レーダ装置の送信パルス信号との干渉を回避する。但し、ＤＦＳ機能は、レーダ装置のパルスパターンを検知した場合に、当該周波数のチャネルの使用を一定時間（例えば３０分間）だけ中断する。一定時間が経過した後には、そのチャネルが再使用され、電波干渉が発生してしまう可能性がある。また、無線LANアクセスポイントのＤＦＳ機能が何らかの原因で有効にならず、その結果電波干渉が発生する可能性がある。 As a measure for avoiding radio wave interference, for example, a wireless LAN access point is equipped with a DFS function. This DFS function determines whether or not a predefined pulse pattern of the radar apparatus is included in the signal received by the access point. The pulse pattern is defined by parameters such as a pulse width, a pulse repetition frequency (pulse repetition interval), and the number of pulses. When it is determined that the pulse pattern is included (when detected), the DFS function avoids interference with the transmission pulse signal of the radar device by changing to a channel of another frequency. However, when the DFS function detects a pulse pattern of the radar apparatus, the DFS function interrupts the use of the channel of the frequency for a predetermined time (for example, 30 minutes). After a certain period of time has elapsed, the channel may be reused and radio wave interference may occur. In addition, the DFS function of the wireless LAN access point may not be effective for some reason, and as a result, radio wave interference may occur.

As shown in FIG. 1, the attachment unit 2 includes a distributor 20, a wireless communication device 21, and a control / analysis device 22. The distributor 20 distributes the radio wave signal received by the antenna unit 10 and amplified by the low noise amplifier 130 of the receiver 13 to the frequency converter 131 and the wireless communication device 21 of the receiver 13. As will be described later, the radio communication device 21 receives a radio signal of a designated frequency (a set channel band) among radio signals from the distributor 20.
　なお、分配器２０はレーダ本体１に内蔵されており、アンテナユニット１０により受信されて、低ノイズ増幅器１３０により増幅された電波信号を、例えばケーブル等を介して無線通信装置２１に出力する構成でもよい。また、制御・解析装置２２はレーダ本体１に内蔵されて、例えばケーブル等を介して無線通信装置２１からの信号を入力する構成でもよい。 The distributor 20 is built in the radar main body 1 and may be configured to output a radio signal received by the antenna unit 10 and amplified by the low noise amplifier 130 to the wireless communication device 21 via, for example, a cable.

　無線通信装置２１は、例えば、無線LANのアクセスポイント（ＡＰ）として使用される既存の無線通信装置である。本実施形態では、無線通信装置２１は、使用チャネルの中で、レーダ本体１が送受信する周波数と同一（又は同様）の周波数に対応するチャネルが設定されて、受信機能のみが有効に設定された状態である。無線通信装置２１は、分配器２０から出力された電波信号の中で、当該設定に基づいて受信した電波信号を、所定の処理後に制御・解析装置２２に出力する。 The wireless communication device 21 is an existing wireless communication device used as, for example, a wireless LAN access point (AP). In the present embodiment, the wireless communication device 21 is set such that the channel corresponding to the same frequency (or similar) as the frequency transmitted and received by the radar main body 1 is set among the used channels, and only the reception function is enabled. State. The radio communication device 21 outputs the radio signal received based on the setting among the radio signals output from the distributor 20 to the control / analysis device 22 after predetermined processing.
　要するに、本実施形態では、無線通信装置２１は、レーダ本体１のアンテナユニット１０により受信された電波信号の中で、レーダ本体１と電波干渉の要因となる周波数の電波信号を、レーダ本体１の受信機１３及び分配器２０を経由して受信する。また、無線通信装置２１は、後述するように、電波干渉の回避処理の対象となる、既設の任意の無線通信装置として、例えば無線LANのＡＰから送信された電波信号を受信する。 In short, in the present embodiment, the radio communication device 21 transmits a radio signal having a frequency that causes radio interference with the radar main body 1 among the radio signals received by the antenna unit 10 of the radar main body 1 to the radar main body 1. Received via the receiver 13 and the distributor 20.

[Operation of radar equipment]
Hereinafter, the operation of the radar apparatus of this embodiment will be described with reference to FIGS. 3 to 6. However, as described above, the description of the normal operation (detection, observation, ranging) in the radar operation is omitted. FIG. 5 is a flowchart for mainly explaining the operation of the appendix 2 in the radar apparatus.
　本実施形態のレーダ装置では、データ処理装置１５は、レーダ運用上の通常動作とは異なる電波干渉の回避機能上の送受信処理を実行する。電波干渉の回避機能上の送受信処理において、図５に示すように、レーダ本体１では、受信機１３は、アンテナユニット１０により受信された電波信号を受信する（ステップＳ１）。受信機１３は、既設の任意の無線通信装置である、例えば無線LANのＡＰから送信されたビーコンを含む電波信号を受信する。 In the radar apparatus of the present embodiment, the data processing apparatus 15 executes transmission / reception processing on a function of avoiding radio wave interference that is different from normal operation in radar operation. In the transmission / reception processing in the radio wave interference avoidance function, as shown in FIG. 5, in the radar main body 1, the receiver 13 receives the radio wave signal received by the antenna unit 10 (step S1). The receiver 13 receives a radio signal including a beacon transmitted from an AP of a wireless LAN, which is an existing arbitrary wireless communication device.
　受信機１３は、アンテナユニット１０により受信されて、低ノイズ増幅器１３０により増幅された電波信号を分配器２０に転送する。分配器２０は、当該電波信号（ビーコンを含む）を周波数変換部１３１及び無線通信装置２１に分配する。無線通信装置２１は、前述したように、分配器２０から出力された電波信号の中で、設定に基づいた指定の周波数（設定されたチャネルの帯域）の電波信号を受信する受信処理を実行する（ステップＳ２）。 The receiver 13 transfers the radio wave signal received by the antenna unit 10 and amplified by the low noise amplifier 130 to the distributor 20. The distributor 20 distributes the radio signal (including the beacon) to the frequency converter 131 and the wireless communication device 21. As described above, the wireless communication device 21 executes a reception process of receiving a radio signal of a specified frequency (a set channel band) based on the setting from among the radio signals output from the distributor 20. (Step S2).
　無線通信装置２１は、分配器２０から出力された電波信号を受信できた場合、所定の処理後に制御・解析装置２２に出力する（ステップＳ３のＹＥＳ）。一方、無線通信装置２１は、当該電波信号以外の電波信号については受信せず、機能しない状態となる（ステップＳ３のＮＯ）。 When the radio communication device 21 can receive the radio signal output from the distributor 20, the wireless communication device 21 outputs the radio signal to the control / analysis device 22 after predetermined processing (YES in step S3). On the other hand, the radio communication device 21 does not receive radio signals other than the radio signal and does not function (NO in step S3).
　制御・解析装置２２は、無線通信装置２１から出力される電波信号を入力し、解析処理を実行する（ステップＳ４）。ここで、本実施形態では、制御・解析装置２２は、電波信号として、無線LANのＡＰから送信されたビーコンから、当該ＡＰを識別する情報を含む各種の情報を抽出するための解析処理を実行する。制御・解析装置２２は、解析結果である情報をデータ処理装置１５に伝達する（ステップＳ５）。 The control / analysis device 22 receives the radio signal output from the wireless communication device 21 and executes an analysis process (step S4). Here, in the present embodiment, the control / analysis device 22 executes an analysis process for extracting various types of information including information for identifying the AP from the beacon transmitted from the wireless LAN AP as a radio wave signal. To do. The control / analysis device 22 transmits information as an analysis result to the data processing device 15 (step S5).
　図６は、レーダ本体１のデータ処理装置１５が実行する処理を説明するためのフローチャートである。 FIG. 6 is a flowchart for explaining processing executed by the data processing device 15 of the radar main body 1.
　データ処理装置１５は、制御・解析装置２２から伝達される解析結果を示す情報に基づいて、電波干渉の回避機能に関する処理を実行する。即ち、データ処理装置１５は、記憶部１５１に格納されたパルスパターンテーブル１５２及びログテーブル１５３を参照して、電波干渉の回避機能に関する処理を実行する。 The data processing device 15 executes processing related to the function of avoiding radio wave interference based on the information indicating the analysis result transmitted from the control / analysis device 22. That is, the data processing device 15 refers to the pulse pattern table 152 and the log table 153 stored in the storage unit 151 and executes processing related to the radio wave interference avoidance function.
　図６に示すように、データ処理装置１５は、制御・解析装置２２から伝達される解析結果を示す情報に基づいて、ログテーブル情報を作成してログテーブル１５３に記録する（ステップＳ１０）。 As shown in FIG. 6, the data processing device 15 creates log table information based on the information indicating the analysis result transmitted from the control / analysis device 22 and records it in the log table 153 (step S10).
　図４は、ログテーブル１５３に記録されるログテーブル情報の一例を示す図である。図４に示すように、ログテーブル情報は、アンテナの仰角及び方位角毎に記録されて、無線通信装置２１により受信されたビーコンに含まれる情報の中で、無線LANのＡＰを識別できる情報等を含む。無線LANのＡＰを識別できる情報としては、例えば、国際規格情報（ＨＴ等）、認証国（ＪＰやＵＳ等）、国内規格情報（技術基準適合認証等の情報）、アドレス情報及びＩＤ情報である。ここで、例えば、ＨＴは、無線LANの国際規格IEEE802.11nを意味する。アドレス情報とは所謂、ＭＡＣアドレスである。ＩＤ情報はＳＳＩＤ(Service Set Identifier)である。さらに、ログテーブル情報は、レーダ本体１から取得される情報として、電波信号の受信強度（dBm）を意味する干渉レベル、及び受信時刻を意味する時刻などの情報を含む。 FIG. 4 is a diagram illustrating an example of log table information recorded in the log table 153. As shown in FIG. 4, the log table information is recorded for each elevation angle and azimuth angle of the antenna, and the information included in the beacon received by the wireless communication device 21 can identify the wireless LAN AP. including. Information that can identify the AP of the wireless LAN includes, for example, international standard information (such as HT), certification country (such as JP and US), domestic standard information (information such as technical standard conformity certification), address information, and ID information. . Here, for example, HT means the international standard IEEE802.11n for wireless LAN. The address information is a so-called MAC address. The ID information is an SSID (Service Set Identifier). Furthermore, the log table information includes information such as an interference level that indicates a reception intensity (dBm) of a radio signal and a time that indicates a reception time as information acquired from the radar main body 1.
　データ処理装置１５は、ログテーブル１５３とは別に、予めパルスパターンテーブル１５２を有する。パルスパターンテーブル１５２は、例えば国の法律や規格等の変更に応じて、オンラインまたはオフラインの方法により新規なタイプのパルスパターンを追加し、または既存のパルスパターンを変更するなどの更新がなされる。 The data processing device 15 has a pulse pattern table 152 in advance separately from the log table 153. The pulse pattern table 152 is updated, for example, by adding a new type of pulse pattern or changing an existing pulse pattern by an online or offline method according to changes in national laws and standards.
　図３は、パルスパターンテーブル１５２に記録されるパルスパターン情報の一例を示す図である。図３に示すように、パルスパターン情報は、ログテーブル情報の国際規格情報（ＨＴ）、認証国（ＪＰ）、国内規格情報毎に設定された、有効パルスパターンを定義した情報である。有効パルスパターンとは、レーダ運用上の通常動作で使用される運用パルスパターンとは別に定義されたものである。即ち、有効パルスパターンとは、電波干渉の回避処理の対象となる、既設の任意の無線通信装置（ここでは無線LANのＡＰ）のＤＦＳ機能により検知されて、ＤＦＳ機能による電波干渉の回避処理の対象となるパルスパターンである。 FIG. 3 is a diagram showing an example of pulse pattern information recorded in the pulse pattern table 152. As shown in FIG. 3, the pulse pattern information is information defining an effective pulse pattern set for each international standard information (HT), certified country (JP), and domestic standard information in the log table information. The effective pulse pattern is defined separately from the operation pulse pattern used in the normal operation for radar operation. That is, the effective pulse pattern is detected by the DFS function of any existing wireless communication apparatus (here, the wireless LAN AP) that is the target of the radio wave interference avoidance process, and the radio wave interference avoidance process by the DFS function. This is a target pulse pattern.
　具体的には、有効パルスパターンは、例えば、気象レーダ用に定義された複数のタイプ（便宜的に、Ｔ１，Ｔ２の２種類とする）のパルスパターンを有する。タイプＴ１，Ｔ２はそれぞれ、パルス幅（PW1,PW2）、パルス繰り返し周波数（PRF1,PRF2）、パルス数（PN1,PN2）、周波数掃引幅（FW1,FW2）等のパラメータにより規定されるパルスパターンである。 Specifically, the effective pulse pattern has, for example, a plurality of types of pulse patterns defined for weather radar (for convenience, two types of T1 and T2). Type T1 and T2 are pulse patterns defined by parameters such as pulse width (PW1, PW2), pulse repetition frequency (PRF1, PRF2), number of pulses (PN1, PN2), frequency sweep width (FW1, FW2), etc. is there.
　図６のフローチャートに戻って、データ処理装置１５は、電波干渉の回避機能上の処理として、ログテーブル情報とパルスパターン情報との照合処理を実行する（ステップＳ１１）。データ処理装置１５は、照合結果により、ログテーブル情報に含まれる国際規格情報、認証国、国内規格情報が一致する有効パルスパターンをパルスパターンテーブル１５２から選択して設定する（ステップＳ１２のＮＯ，Ｓ１３）。ここで、データ処理装置１５は、照合処理による照合が不可能な場合には、オンラインまたはオフラインの方法によりパルスパターンテーブル１５２を更新する処理を実行してもよい（ステップＳ１２のＹＥＳ，Ｓ１５）。 Referring back to the flowchart of FIG. 6, the data processing device 15 executes a collation process between the log table information and the pulse pattern information as a process on the radio wave interference avoiding function (step S11). The data processing device 15 selects and sets an effective pulse pattern that matches the international standard information, the authentication country, and the national standard information included in the log table information from the pulse pattern table 152 based on the collation result (NO in step S12, S13). ). Here, when collation by collation processing is impossible, the data processor 15 may perform the process which updates the pulse pattern table 152 by an online or offline method (YES of step S12, S15).
　以下、有効パルスパターンの設定処理を具体的に説明する。 Hereinafter, the effective pulse pattern setting process will be described in detail.
　データ処理装置１５は、照合処理の前処理として、図４に示すログテーブル１５３を参照し、ログテーブル情報において、同じアドレス情報及びＩＤ情報を含む複数の仰角及び方位角毎の情報から、干渉レベルが最も強い仰角及び方位角の情報を選択する。ここで、干渉レベルが最も強い仰角及び方位角とは、無線LANのＡＰからの電波信号（ビーコン）に対する受信強度が強い方向（仰角及び方位角）を意味する。従って、当該仰角及び方位角のアンテナから送信する有効パルスパターンが、無線LANのＡＰのＤＦＳ機能に対して最も有効となる。 The data processing device 15 refers to the log table 153 shown in FIG. 4 as preprocessing of the collation processing, and in the log table information, from the information for each of the plurality of elevation angles and azimuth angles including the same address information and ID information, the interference level Selects the information of the strongest elevation and azimuth. Here, the elevation angle and azimuth angle at which the interference level is the strongest means a direction (elevation angle and azimuth angle) in which the reception intensity with respect to the radio signal (beacon) from the AP of the wireless LAN is strong. Therefore, the effective pulse pattern transmitted from the antenna of the elevation angle and the azimuth angle is most effective for the DFS function of the wireless LAN AP.
　データ処理装置１５は、選択した仰角及び方位角に対応する、ログテーブル情報の国際規格情報、認証国、国内規格情報を使用して、パルスパターン情報との照合処理を実行する。これにより、データ処理装置１５は、パルスパターンテーブル１５２から照合する有効パルスパターン（例えばＴ１）を設定する。 The data processing device 15 performs collation processing with the pulse pattern information using the international standard information, the certification country, and the domestic standard information of the log table information corresponding to the selected elevation angle and azimuth. Accordingly, the data processing device 15 sets an effective pulse pattern (for example, T1) to be collated from the pulse pattern table 152.
　データ処理装置１５は、設定した有効パルスパターン（Ｔ１）を信号処理装置１４に出力して、前述したように、無線LANのＡＰのＤＦＳ機能に対して最も有効となる方向（アンテナの仰角及び方位角）に送信する送信処理を実行する（ステップＳ１４）。即ち、信号処理装置１４は、データ処理装置１５により設定された有効パルスパターン（Ｔ１）を送信機１２に出力して、送信処理を実行する。レーダ本体１では、送信機１２は有効パルスパターンに応じた送信パルスを生成してアンテナユニット１０に出力する。これにより、レーダ本体１は、アンテナユニット１０から最も有効となる仰角及び方位角のアンテナから送信パルスに応じた電波信号を送信する。 The data processing device 15 outputs the set effective pulse pattern (T1) to the signal processing device 14 and, as described above, the direction most effective for the DFS function of the AP of the wireless LAN (the elevation angle and direction of the antenna). A transmission process to transmit to (corner) is executed (step S14). That is, the signal processing device 14 outputs the effective pulse pattern (T1) set by the data processing device 15 to the transmitter 12, and executes transmission processing. In the radar main body 1, the transmitter 12 generates a transmission pulse corresponding to the effective pulse pattern and outputs it to the antenna unit 10. Thereby, the radar main body 1 transmits a radio wave signal corresponding to the transmission pulse from the antenna having the most effective elevation angle and azimuth angle from the antenna unit 10.
　以上のように本実施形態によれば、電波干渉の回避機能上の受信処理時に、無線通信装置２１の受信機能を利用して、既設の任意の無線通信装置（無線LANのＡＰ）から送信された電波信号を受信する。この場合、無線通信装置２１は、指定の周波数（設定されたチャネルの帯域）の電波信号、即ち、レーダ本体１と電波干渉の要因となる周波数の電波信号（ビーコン）のみを受信する。従って、データ処理装置１５は、制御・解析装置２２から、当該受信信号（ビーコン）の解析結果の情報（無線LANのＡＰの識別情報等を含む）を入力した時点で、レーダ本体１と電波干渉の要因となる無線LANのＡＰの存在を認識することになる。従って、制御・解析装置２２としては、当該電波信号を解析処理する際に、レーダ本体１との電波干渉の判定処理を行うような特別の機能は不要である。 As described above, according to the present embodiment, at the time of reception processing on the radio wave interference avoidance function, the reception function of the wireless communication device 21 is used to transmit from any existing wireless communication device (wireless LAN AP). Receive radio signals. In this case, the wireless communication device 21 receives only a radio signal having a specified frequency (a set channel band), that is, a radio signal (beacon) having a frequency that causes radio interference with the radar main body 1. Therefore, the data processing device 15 and the radio wave interference with the radar main body 1 when the information (including the identification information of the wireless LAN AP) of the received signal (beacon) is input from the control / analysis device 22. The presence of a wireless LAN AP, which is a cause of this, is recognized. Therefore, the control / analysis device 22 does not need a special function for performing the process of determining the radio wave interference with the radar main body 1 when the radio wave signal is analyzed.
　データ処理装置１５は、パルスパターンテーブル１５２及びログテーブル１５３を参照して、各情報の照合処理に基づいて有効パルスパターンを設定し、無線LANのＡＰのＤＦＳ機能に対して最も有効となる方向（アンテナの仰角及び方位角）に送信する送信処理を実行できる。即ち、当該有効パルスパターンを使用した電波干渉の回避機能上の送信処理を実行できる。ここで、任意の無線通信装置である無線LANのＡＰは、ＤＦＳ機能により、例えばタイプＴ１の有効パルスパターンに応じた電波信号を検知し、当該電波信号（レーダ装置からの送信電波）との間で電波干渉の可能性がある周波数（チャネル帯域）の電波信号の送信停止や、チャネル切り替え処理を実行する。 The data processing device 15 refers to the pulse pattern table 152 and the log table 153, sets an effective pulse pattern based on the collation processing of each information, and the direction that is most effective for the DFS function of the wireless LAN AP ( It is possible to execute transmission processing for transmission to the elevation angle and azimuth angle of the antenna. That is, it is possible to execute transmission processing on the function of avoiding radio wave interference using the effective pulse pattern. Here, the wireless LAN AP, which is an arbitrary wireless communication device, detects a radio wave signal corresponding to an effective pulse pattern of type T1, for example, with the DFS function, and detects the radio wave signal (transmitted radio wave from the radar device). , Stop transmission of radio signals of frequencies (channel band) that may cause radio wave interference, and execute channel switching processing.
　このような電波干渉の回避機能上の送信処理により、任意の無線通信装置（無線LANのＡＰ）は、ＤＦＳ機能により有効パルスパターンに応じた電波信号を検知することで、結果としてレーダ装置の存在を認識し、電波干渉を回避するための処理を行う可能性が高い。換言すれば、任意の無線通信装置に含まれるＤＦＳ機能を利用することで、レーダ本体１は、任意の無線通信装置の使用周波数を、結果として、レーダ本体１の使用周波数とは異なる周波数に誘導させることが可能となる。従って、レーダ本体１と、任意の無線通信装置との間での電波干渉を回避することが可能となる。 By such transmission processing on the radio wave interference avoidance function, an arbitrary radio communication device (AP of the wireless LAN) detects a radio wave signal corresponding to the effective pulse pattern by the DFS function, and as a result, the presence of the radar device. Is likely to perform processing for recognizing and avoiding radio wave interference. In other words, by using the DFS function included in an arbitrary radio communication device, the radar main body 1 guides the use frequency of the arbitrary radio communication device to a frequency different from the use frequency of the radar main body 1 as a result. It becomes possible to make it. Therefore, it is possible to avoid radio wave interference between the radar main body 1 and an arbitrary wireless communication device.
　さらに、本実施形態によれば、データ処理装置１５は、図４に示すようなログテーブル１５３を参照して、電波干渉を検出した場合に、仰角、方位角、及び受信時刻等に基づいて、有効パルスパターンを定期的に送信する電波干渉の回避機能上の送信処理を実行することにより、電波干渉の回避機能を効果的に発揮できる。 Further, according to the present embodiment, the data processing device 15 refers to the log table 153 as shown in FIG. 4 and detects radio wave interference based on the elevation angle, the azimuth angle, the reception time, and the like. By executing the transmission process on the radio wave interference avoidance function that periodically transmits the effective pulse pattern, the radio wave interference avoidance function can be effectively exhibited.
　また、本実施形態によれば、データ処理装置１５は、制御・解析装置２２からの解析結果を示す情報から、任意の無線通信装置（無線LANのＡＰ）の国際規格、認証国、国内規格等の情報を取得し、ログテーブル１５３に記録できる。従って、データ処理装置１５は、これらの情報に基づいて、電波干渉を起こす可能性のある無線LANのＡＰの仕様や存在を認識できる。これにより、例えば、レーダ装置の運用側において、既設の任意の無線LANのＡＰに対して、電波干渉を回避するための効果的な対策を実現できる可能性がある。具体例として、当該無線LANのＡＰの国際規格、認証国、国内規格に対応する有効パルスパターンの全てを送信しても良い。

Can be acquired and recorded in the log table 153. Therefore, the data processing device 15 can recognize the specification and existence of the wireless LAN AP that may cause radio wave interference based on the information. Thereby, for example, on the operation side of the radar device, there is a possibility that an effective measure for avoiding radio wave interference may be realized for any existing wireless LAN AP. As a specific example, all effective pulse patterns corresponding to the international standard, the certification country, and the domestic standard of the AP of the wireless LAN may be transmitted.
