具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
附图中所示的流程图仅是示例说明,不是必须包括所有的内容和操作/步骤,也不是必须按所描述的顺序执行。例如,有的操作/步骤还可以分解、组合或部分合并,因此实际执行的顺序有可能根据实际情况改变。
下面结合附图,对本申请的一些实施方式作详细说明。在不冲突的情况下,下述的实施例及实施例中的特征可以相互组合。
本申请的实施例提供了一种雷达的抗干扰方法、可移动平台、遥控器、控制系统及存储介质,用于提高搭载在可移动平台上的雷达抗干扰能力,从而确保可移动平台的安全运行。其中,控制系统包括可移动平台和遥控设备等。
示例性的,如图1所示,控制系统可以为飞行系统,该飞行系统包括遥控器和飞行器,遥控器用于控制飞行器的飞行或执行相应的动作,并从飞行器中获取相应的运动信息,该运动信息为飞行器的飞行运动信息,比如运动方向、运动姿态、运动速度和/或位置信息等等。
示例性的,可移动平台包括飞行器、机器人或自动驾驶车辆等。
其中,飞行器包括无人机,该无人机包括旋翼型无人机,例如四旋翼无人机、六旋翼无人机、八旋翼无人机,也可以是固定翼无人机,还可以是旋翼型与固定翼无人机的组合,在此不作限定。
示例性的,遥控设备包括遥控器、地面控制平台、手机、平板电脑、笔记本电脑和PC电脑等,在此不作限定。
其中,遥控设备用于控制可移动平台的飞行或执行某种动作,比如执行拍摄或测量等。如图1所示,一个遥控器可以控制多架飞行器,即一控多机。
需要说明的是,在本申请的实施例中,将以图1中的飞行系统对本申请提供的雷达的抗干扰方法进行介绍,但图1对应方式并不构成对本申请提供的控制系统的限定。
其中,可移动平台上搭载有雷达,雷达用于实现测速、测距、探测、跟踪、定位以及识别等功能。雷达主要包括射频前端模块和信号处理模块,射频前端模块包括一个发射天线和一个接收天线,信号处理模块负责产生调制信号以及对采集的中频信号进行处理分析。
具体地,射频前端模块接收到调制信号产生频率随调制信号线性变化的高频信号,通过发射天线向下辐射,电磁波遇到地面、目标物或障碍物被反射回来,再被接收天线接收,发射信号与中频进行混频得到中频信号,根据中频信号的频率就可得到速度信息和距离信息。
雷达通过辐射电磁波在空间中传播遇到目标物,由目标物散射回波被雷达接收实现探测目标物。因此满足一定条件的电磁设备的电磁波均可以进入接收天线,影响雷达的性能,使雷达探测性能下降,无法获得探测、跟踪、定位以及识别等信息,或者有用的信息淹没在许多干扰信号中,无法提取真正信息。
当某个区域范围存在多个雷达同时工作时,会存在相互干扰概率,当有两个雷达(比如雷达1和雷达2)发射调制近似同步,如图2所示,T 1为雷达1发射调制波形,T 2为雷达2发射调制波形,T 3为雷达1接收调制波形,f 1为雷达1和雷达2产生的干扰频率,f 2为雷达1发射目标频率。在图2中,雷达1和雷达2发射波形近似,其混频产生的基带信号可能落入检测频带带宽内,被接收天线接收并通过信号处理模块处理检测,形成虚假目标。如果干扰频率能量过大而真实目标能量较小,可能形成遮蔽效应,进而影响雷达的检测性能,即形成了同步干扰。
当两个雷达同时工作,可能会出现burst干扰。如图3所示,两个雷达发射啁啾信号,边沿的间隔超过了截止频带f_cutoff,但是仍然存在一段交叉的时间部分Delta_t,其中f_cutoff的时间长度为:
Figure PCTCN2019110202-appb-000001
其中,k为调制斜率,即带宽与调制时间的比值。当雷达得到发生电磁波处于上述情况(图3中波形)下可能会产生burst干扰。
两个雷达的受干扰具体可在时域或频域进行表示,如图4a和图4b所示,为两个雷达的时域信号受干扰示意图。对时域信号做快速傅里叶变换(FFT),得到两个雷达的频域信息受干扰示意图,分别如图5a和图5b所示。去除时域干扰后的频域信号,如图6a和图6b所示。
从图4a、图4b、图5a和图5b可以看出,时域上突变信号(干扰信号)会导致频域整个底噪抬升。对比去除时域干扰信号再做FFT变换到频域,如图6a和图6b所示,其底噪下降10-20dB。当在一个中频信号的采集长度内出现burst干扰,从图中可以看出,其burst干扰信号本身也是线性调频信号(LFM),其频率随着干扰时刻变化,是一种典型的非平稳信号,如果对含有此信号的回波进行FFT分析将产生严重误差,导致检测异常、失效,进而影响可移动平台的安全运行。
示例性的,当某一位置区域出现多个飞行器时,尤其是密集区域有多个装配有雷达的飞行器进行飞行时,比如一控多机的情形,或者多个飞行器执行协同工作,极有可能出现雷达之间的干扰,比如同步干扰和burst干扰等,严重影响飞行器的作业和飞行安全。因此有必要提高飞行器的雷达之间的抗干扰能力,以确保飞行器的飞行安全。
请参阅图7,图7是本申请一实施例提供的一种雷达的抗干扰方法的步骤示意流程图。该方法可以应用于遥控设备中,用于对可移动平台的雷达进行参数配置,以提高雷达的抗扰能力。
如图7所示,该基于雷达的抗干扰方法包括步骤S101至步骤S104。
S101、确定多个可移动平台是否处于协同作业模式。
协同作业模式可以为多个可移动平台协同工作的模式,谓协同,就是指协调两个或者两个以上的不同资源或者个体,协同一致地完成某一目标的过程或能力。
示例性的,比如多个飞行器执行表演、多个农业植保机执行喷洒作业、多个飞行器执行巡检或一控多机等场景,均可认为是协同作业模式。
在一些实施例中,确定多个可移动平台是否处于协同作业模式,具体为:确定多个可移动平台是否由一个遥控设备控制;若所述多个可移动平台由一个 遥控设备控制,则确定所述多个可移动平台处于所述协同作业模式。
比如,如图1所示,多个飞行器由同一个遥控器控制,因此可以确定图1中的多个飞行器处于所述协同作业模式。由此可以针对处于一控多机模式的飞行器进行雷达参数配置,以提高一控多机模式的飞行器的雷达抗干扰能力。
可以理解的是,一控多机可以是一个遥控设备控制的多个飞行器,比如为两个飞行器或更多个飞行器等。
在一些实施例中,确定多个可移动平台是否处于协同作业模式,具体为:确定多个可移动平台是否处于预设区域范围内工作;若所述多个可移动平台处于所述预设区域范围内工作,则确定所述多个可移动平台处于所述协同作业模式。
例如,预设区域范围可以表示一个飞行范围,比如5Km范围内或者10Km范围内等等。
示例性的,以一个目标物设置一个预设区域范围,根据可移动平台的飞行位置确定预设区域范围内是否存在多个可移动平台,若预设区域范围内存在多个可移动平台,则确定所述多个可移动平台处于所述协同作业模式。
比如,以某一个铁塔为目标物,在距离该目标物5km范围内的多个可移动平台可认为处于所述协同作业模式,并且认为该多个可移动平台有可能存在雷达干扰。
示例性的,也可以从多个可移动平台的飞行位置确定一个中心位置,根据该中心位置确定预设区域范围;若是该预设区域范围存在多个可移动平台,则认为多个可移动平台处于所述协同作业模式。
比如,存在5个可移动平台同时作业,分别为可移动平台A、可移动平台B、可移动平台C、可移动平台D和可移动平台E。假如以可移动平台A为中心,若可移动平台B、可移动平台C、可移动平台D和可移动平台E距离可移动平台A的距离均小于5Km范围内,则确定5个可移动平台处于协同作业模式。
S102、若所述多个可移动平台处于所述协同作业模式,获取所述多个可移动平台的运动信息。
其中,所述运动信息包括:运动方向、运动姿态、运动速度和/或位置信息等等。当然,运动信息还可包括其他信息,比如可移动平台的标识信息,用于 区别不同的可移动平台。
若可移动平台为飞行器,所述运动姿态为飞行姿态角,具体包括航向角、俯仰角和横滚角。所述位置信息包括经度信息和维度信息。
具体地,可以由每个可移动平台采集其运动信息,并将该运动信息发送至遥控设备,该遥控设备接收并获取所述多个可移动平台的运动信息。
S103、根据所述运动信息确定至少一个可移动平台的雷达配置参数。
根据所述运动信息确定至少一个可移动平台的雷达配置参数,即根据运动信息重新配置至少一个可移动平台的雷达配置参数。
重新配置的雷达配置参数包括不同的极化方式、频带带宽和/或调制波形。所述极化方式包括:正45°极化、负45°极化、水平极化和/或垂直极化。
其中,正45°极化如图8a中的A1所示,负45°极化如图8a中的A2所示。在一实施方式中,雷达天线的极化方式可采用正45°极化或负45°极化的组合;在另一实施方式中,雷达天线的极化方式采用水平极化或垂直极化的组合。比如雷达配置参数不采用正45°极化和水平极化的组合。
频带带宽是指将雷达工作的总带宽划分为多个子带宽,具体如图8b所示,将总带宽B划分三个子带宽,分别为ΔB1、ΔB2和ΔB3,每个雷达的子带宽均可作为雷达工作的频带带宽。
在一个实施例中,为了提高雷达的抗扰能力,可采用正45°极化或负45°极化的变极化方式,假如频带带宽包括ΔB1、ΔB2和ΔB3,则相应地雷达配置参数可最多包括6组雷达配置参数,如表1所示:
表1为不同的雷达配置参数
A1、ΔB1 A1、ΔB2 A1、ΔB3
A2、ΔB1 A2、ΔB2 A2、ΔB3
采用正45°极化或负45°极化方式,可以进一步地提高可移动平台的雷达抗干扰能力。比如,为两个可移动平台重新配置的雷达配置参数分别为A1、ΔB1和A1、ΔB2,电磁波均是采用正45°极化(A1)方式发射,当两个飞行器相对飞行时,接收到的电磁波由于是采用正45°极化,因此接收到的彼此发射的电磁波的回波是正交的,由此可以提高飞行器的抗干扰能力,而水平极化和垂直极化达不到这种效果。
其中,调制波形包括具有相同时间间隙的调制波形或具有不同时间间隙的 调制波形。其中,具有相同时间间隙的调制波形,即两个调制波形的时间间隙相同,具体如图8c所示,图8c中的调制波形可以表示为W1;具有不同时间间隙的调制波形,即两个调制波形的时间间隙不同,具体如图8d所示,图8d中的调制波形可以表示为W2。
在另一实施例中,为了提高雷达的抗扰能力,采用两种调制波形(W1和W2),假如频带带宽包括ΔB1、ΔB2和ΔB3,则相应地雷达配置参数最多包括6组不同的雷达配置参数,具体如表2所示:
表2为不同的雷达配置参数
W1、ΔB1 W1、ΔB2 W1、ΔB3
W2、ΔB1 W2、ΔB2 W2、ΔB3
可以理解的是,雷达配置参数除了包括表1和表2中类型外,也可以是极化方式、频带带宽和调制波形三种不同参数的组合,以得到更多组不同的雷达配置参数。以便为更多可移动平台分配雷达配置参数。
为了便于分配,可以对各组雷达配置参数进行标记,得到每组雷达配置参数的标记。比如,1#表示W1、ΔB1;2#表示W1、ΔB2;3#表示W1、ΔB3;4#表示W2、ΔB1;5#表示W2、ΔB2;6#表示W2、ΔB3,当然也用其他编号进行标记,在此不做限定。
不同的雷达配置参数由于极化方式、频带带宽或/或调制波形不同,可以降低不同雷达的彼此干扰,比如可以避免出现同步干扰或burst干扰。
由此可以根据上述多组雷达配置参数为处于所述协同作业模式的多个可移动平台分配雷达配置参数,以提高可移动平台的雷达抗干扰能力。
在一些实施例中,根据所述运动信息确定至少一个可移动平台的雷达配置参数,具体为:根据所述多个可移动平台的数量确定对应的参数分配规则,再根据确定的参数分配规则为所述多个可移动平台分配雷达配置参数。
具体地,多个可移动平台的数量可以由遥控设备进行确定,比如为一控多机模式,遥控设备获取其控制的可移动平台的具体数量;当然,也可以根据接收到的运动信息确定多个可移动平台的数量,比如接收到多少个可移动平台发送的信号,则可以确定多个可移动平台的具体数量。
参数分配规则为预先设置的分配规则,可以包括多个分配规则,具体由可移动平台的数量确定,以便为多个可移动平台分配合适的雷达配置参数,进而 提高可移动平台的雷达抗干扰能力。
示例性的,可由可移动平台的数量确定分配规则,具体为:判断所述多个可移动平台的数量是否大于预设数目;若所述多个可移动平台的数量大于所述预设数目,确定使用第一参数分配规则为所述多个可移动平台分配雷达配置参数;若所述多个可移动平台的数量小于或等于所述预设数目,确定使用第二参数分配规则为所述多个可移动平台分配雷达配置参数;其中,所述第一参数分配规则与所述第二参数分配规则不同。根据可移动平台数量的多少选择不同的分配规则,以提高雷达配置参数的分配效率和合理性,进而提高可移动平台的雷达抗干扰能力。
需要说明的是,预设数目为最多可以不重复分配的雷达配置参数,比如表1和表2,对应的预设数目均为6。
在一个实施例中,如图9所示,可依据第一参数分配规则确定所述至少一个可移动平台的雷达配置参数,具体包括以下步骤:
S103a、获取预先设置的雷达配置参数组;
S103b、根据所述运动信息中的位置信息对所述多个可移动平台进行分区,得到每个所述可移动平台对应的任务区域;
S103c、根据所述雷达配置参数组和所述任务区域为每个所述可移动平台分配一组雷达配置参数。
其中,所述雷达配置参数组包括多组不同的雷达配置参数,比如表2所示,雷达配置参数组中包括6组雷达配置参数,分别为1#、2#、3#、4#、5#和6#。
根据所述运动信息中的位置信息对所述多个可移动平台进行分区,得到每个所述可移动平台对应的任务区域。具体地,可根据可移动平台的位置信息进行区域划分,得到每一个可移动平台对应的任务区域。
比如,如图10a所示,根据7个可移动平台的位置信息进行区域划分,得到每一个可移动平台对应的任务区域,即图10a中的7个任务区域,分别表示为:任务区域1、任务区域2、任务区域3、任务区域4、任务区域5、任务区域6和任务区域7,分别对应着可移动平台1、可移动平台2、可移动平台3、可移动平台4、可移动平台5、可移动平台6和可移动平台7。
采用所述雷达配置参数组中的雷达配置参数为每个所述可移动平台分配一组雷达配置参数,且确保每个所述任务区域对应的可移动平台分配的雷达配置 参数与相邻任务区域对应的可移动平台分配的雷达配置参数不同。由此可以快速地为每一个可移动平台分配一组雷达配置参数,且确保相邻区域的可移动平台分配的雷达配置参数不重复,由此提高了可移动平台的雷达抗干扰能力。
在实际应用中,步骤S103c具体为:根据每个所述可移动平台的可移动平台标识对所述可移动平台对应的任务区域进行标记;根据所述雷达配置参数组中的多组雷达配置参数为每个所述可移动平台试探分配一组雷达配置参数;判断所述任务区域对应的可移动平台分配的雷达配置参数与相邻任务区域对应的可移动平台分配的雷达配置参数是否相同;若所述任务区域对应的可移动平台分配的雷达配置参数与相邻任务区域对应的可移动平台分配的雷达配置参数均不相同,则对所述可移动平台的任务区域进行标记;重复执行所述根据每个所述可移动平台的可移动平台标识对所述可移动平台对应的任务区域进行标记的步骤,直至所述多个可移动平台对应的任务区域均标记完时,得到所述多个可移动平台的雷达配置参数。
根据每个所述可移动平台的可移动平台标识对所述可移动平台对应的任务区域进行标记,具体如图10a所示。
可以根据所述雷达配置参数组中的多组雷达配置参数排序顺序为每个所述可移动平台试探分配一组雷达配置参数,比如从任务区域1开始逐个用参数1#、2#、3#、4#、5#和6#进行试探分配,若当前可移动平台所对应的任务区域与相邻的任务区域分配的雷达配置参数均不相同时,则用栈标标记该任务区域对应的雷达配置参数;若当前可移动平台所对应的任务区域与相邻的任务区域分配的雷达配置参数相同时,则不进行标记,并重复进行下一次试探分配。
其中,具体栈标标记可以不同的序号进行标记,当然可以采用其他标记方式,比如使用不同的颜色标记等。
采用试探分配,分配结果如图10b所示,任务区域3和任务区域7都分配了雷达配置参数2#,但是任务区域3和任务区域7并不相邻,因此依然可以提高雷达的抗干扰能力。
在一个实施例中,如图11所示,还可以依据第二参数分配规则确定所述至少一个可移动平台的雷达配置参数,具体包括以下步骤:
S103e、获取预先设置的雷达配置参数组;
S103f、根据所述雷达配置参数组中的多组雷达配置参数随机为每个所述可 移动平台分配一组雷达配置参数。
需要说明的是,第二参数分配规则的优选的应用场景为预设的雷达配置参数组的雷达配置参数的数量大于可移动平台的数量时。
其中,所述雷达配置参数组包括多组不同的雷达配置参数。比如,如表1和表2所示,均包括6组雷达配置参数。根据所述雷达配置参数组中的多组雷达配置参数随机为每个所述可移动平台分配一组雷达配置参数,以使得每个所述可移动平台分配的雷达配置参数均不相同。
在实际实施中,假如多个可移动平台的数量为5个,分别表示为可移动平台A、可移动平台B、可移动平台C、可移动平台D和可移动平台E,从6组雷达配置参数中随机选择一组雷达配置参数分配给可移动平台A,比如分配了参数2#,则将参数2#进行标记或从所述雷达配置参数组删除;在剩下的5组雷达配置参数中随机选择一组雷达配置参数分配给可移动平台B,直至每一个可移动平台均分配到雷达配置参数,并且每个所述可移动平台分配的雷达配置参数均不相同。
在一个实施例中,当然也可以在根据所述雷达配置参数组中的多组雷达配置参数随机为每个所述可移动平台分配一组雷达配置参数之后,判断是否存在两个所述可移动平台分配的雷达配置参数相同;若存在两个所述可移动平台分配的雷达配置参数相同,则从所述雷达配置参数组随机分配一组雷达配置参数,直至每个所述可移动平台分配的雷达配置参数均不相同。
S104、发送所述雷达配置参数至所述至少一个可移动平台进行雷达参数配置,以提高所述多个可移动平台的雷达抗干扰能力。
其中,可移动平台进行雷达参数配置,即可移动平台将接收的雷达配置参数发送给其搭载的雷达,以使雷达根据所述雷达参数配置发射电磁波。比如,使用正45°极化(A1)方式和子频带ΔB1发射电磁波;或者,使用调制波形W1和子频带ΔB1发射电磁波。
可移动平台将接收的雷达配置参数发送给其搭载的雷达,可以通过通信总线将接收的雷达配置参数发送给其搭载的雷达。通信总线包括CAN总线等,用于电连接可移动平台的控制模块和雷达。
需要说明的是,对所述至少一个可移动平台进行雷达参数配置,可以提高所述多个可移动平台的雷达抗干扰能力,是指在多个可移动平台中重新配置部 分可移动平台的雷达配置参数,提高所述多个可移动平台的雷达抗干扰能力。
比如,两个可移动平台中,只对其中一个可移动平台进行雷达参数配置,由此提高两个可移动平台的雷达抗干扰能力。
上述实施例通过确定多个可移动平台是否处于协同作业模式,在确定多个可移动平台处于协同作业模式时,获取所述多个可移动平台的运动信息;根据所述运动信息确定至少一个可移动平台的雷达配置参数;并发送所述雷达配置参数至所述至少一个可移动平台进行雷达参数配置,以提高所述多个可移动平台的雷达抗干扰能力。比如使用配置后的雷达进行探测或测距等,由于是根据所述多个运动信息确定雷达配置参数并进行重新配置,由此可以避免雷达之间的干扰,进而提高了可移动平台的雷达抗干扰能力,确保了可移动平台的安全运行。
