背景技术Background technique
现有的故障检测与诊断主要利用伪随机码对通信分机进行测试，根据测试结果判定通信分机的故障。虽然该方法具有一定的通用性，但伪随机码产生过程复杂，且其测试精度和准确度两个指标的测量结果随不同雷达装备而有所变化，检测结果的判定受人为主观影响较大，检测判定特征不稳定，最终导致检测结果的准确度不高，且具有较高的故障虚警告率。The existing fault detection and diagnosis mainly uses pseudo-random codes to test the communication extension, and determines the failure of the communication extension according to the test result.

The detection and judgment features are unstable, which eventually leads to the low accuracy of the detection results and a high fault false warning rate.

图1为本发明实施例通信分机加解密模块的故障检测方法流程图，如图1所示，所述方法包括：FIG. 1 is a flowchart of a fault detection method for a communication extension encryption and decryption module according to an embodiment of the present invention. As shown in FIG. 1 , the method includes:
步骤101：获取伪随机码。Step 101: Obtain a pseudo-random code.
具体的，用信号产生模块产生通用伪随机码，将伪随机码灌入加解密模块的输入端，在输出端采集压缩后的伪随机码，对通用伪随机码的压缩速率、压缩数据正确率进行测量。(伪随机码通过直接数字合成的方式产生。)Specifically, a general pseudo-random code is generated by a signal generation module, the pseudo-random code is poured into the input end of the encryption and decryption module, and the compressed pseudo-random code is collected at the output end, and the compression rate of the general pseudo-random code and the correct rate of compressed data are calculated. Take measurements. (Pseudo-random codes are generated by means of direct digital synthesis.)
步骤102：确定所述伪随机码的压缩速率和压缩数据正确率。Step 102: Determine the compression rate of the pseudo-random code and the correct rate of compressed data.
压缩速率计算方法如下：The compression rate is calculated as follows:
输入伪随机码的开始时间为t1，加解密端输出压缩后的伪随机码的时间为t2，则压缩速率v为，v＝1/(t2-t1)；The starting time of the input pseudo-random code is t 1 , and the time for the encryption and decryption terminals to output the compressed pseudo-random code is t 2 , then the compression rate v is, v=1/(t 2 -t 1 );
压缩数据正确率测量方法如下：The compression data accuracy rate measurement method is as follows:
输入端的伪随机码输入的信号中总共有u个1，压缩后的伪随机码中有r个1，则压缩数据正确率w为，w＝r/u。There are u 1's in the signal input by the pseudo-random code at the input terminal, and there are r 1's in the compressed pseudo-random code, then the correct rate w of the compressed data is, w=r/u.
步骤103：获取复杂信号；所述复杂信号为复杂线性调频信号或复杂步进频信号。Step 103: Obtain a complex signal; the complex signal is a complex linear frequency modulation signal or a complex stepped frequency signal.
具体的，复杂线性调频信号的获取具体采用以下方法：Specifically, the acquisition of the complex linear frequency modulation signal specifically adopts the following method:
用信号产生模块产生专用的复杂线性调频信号，(采用直接数字合成的方式产生线性调频信号，线性调频信号的参数与雷达型号有关，不同雷达型号有不同的线性调频信号参数)将线性调频信号灌入加解密模块(具体方法是离线非原位测试，即将该加解密模块从雷达上拆卸下来后，在输入端通过SMA连接输入相应的测试信号，即所谓的灌入到加解密模块)的输入端，在输出端采集压缩后的线性调频信号，对线性调频信号的压缩率、压缩融合率进行测量。Use the signal generation module to generate a dedicated complex linear frequency modulation signal, (using the direct digital synthesis method to generate the linear frequency modulation signal, the parameters of the linear frequency modulation signal are related to the radar model, and different radar models have different linear frequency modulation signal parameters) to fill the linear frequency modulation signal. Enter the input of the encryption and decryption module (the specific method is the off-line non-in-situ test, that is, after the encryption and decryption module is removed from the radar, the corresponding test signal is input through the SMA connection at the input end, that is, the so-called pouring into the encryption and decryption module). At the output end, the compressed linear frequency modulation signal is collected, and the compression rate and compression fusion rate of the linear frequency modulation signal are measured.
复杂步进频信号的获取具体采用以下方法：The acquisition of the complex step frequency signal specifically adopts the following methods:
用信号产生模块产生专用的复杂步进频信号(步进频信号是一种信号形势，产生方法也是利用直接数字合成的方式进行，所需的参数与雷达型号有关，不同的雷达型号对应不同的信号产生参数)将步进频信号灌入加解密模块的输入端，在输出端采集压缩后的步进频信号，对步进频信号的压缩率、压缩融合率进行测量。Use the signal generation module to generate a dedicated complex stepping frequency signal (the stepping frequency signal is a kind of signal situation, and the generation method is also carried out by direct digital synthesis. The required parameters are related to the radar model, and different radar models correspond to different ones. Signal generation parameters) pour the stepping frequency signal into the input end of the encryption and decryption module, collect the compressed stepping frequency signal at the output end, and measure the compression rate and compression fusion rate of the stepping frequency signal.
步骤104：确定所述复杂信号的压缩率和压缩融合率。Step 104: Determine the compression ratio and compression fusion ratio of the complex signal.
复杂线性调频信号的压缩率测量方法如下：The compression ratio measurement method for complex chirp signals is as follows:
输入端的伪随机码信号的时间长度是已知的，假设为x。加解密模块输出端的伪随机码压缩信号的时间长度测量方法如下：先对信号进行采样，然后利用软件处理的方法，测量信号的时间长度，假设为y，则压缩率z的计算方式为：z＝y/x；The time length of the pseudo-random code signal at the input is known, let's say x. The method for measuring the time length of the pseudo-random code compressed signal at the output of the encryption and decryption module is as follows: first sample the signal, and then use the software processing method to measure the time length of the signal. Assuming y, the calculation method of the compression rate z is: z =y/x;
复杂线性调频信号的压缩融合率k为，k＝y/(x+y)。The compression fusion rate k of the complex chirp signal is, k=y/(x+y).
所述复杂步进频信号的压缩率和压缩融合率的测量方法与所述复杂线性调频信号的压缩率和压缩融合率的测量方法一致，此处不再一一赘述。The measurement method of the compression ratio and the compression fusion ratio of the complex stepped frequency signal is the same as the measurement method of the compression ratio and the compression fusion ratio of the complex chirp signal, and will not be repeated here.
