摘要
为了解决外辐射源雷达在较长的积累时间下带来的距离徙动问题,根据外辐射源雷达特点,给出了一种等效频域脉冲压缩与Keystone变换结合的方法,对外辐射源雷达在目标检测的距离徙动进行矫正。并且以DTMB信号作为外辐射源,针对Keystone算法三种实现方法的效率进行了仿真分析,验证了算法在外辐射源雷达中应用的可行性。
In order to solve the problem of range migration caused by long integration timein passive radar,this paper presents a method combining the equivalent frequency domain pulse compression and the Keystone transform according to the characteristics of passive radar,whichcan corrects the range migration in the target detection of passive radar.Moreover,theDTMB signal is used as the transmitting signal,and the efficiency of three implementation methods of keystone algorithm is simulated and analyzed,which verifies the feasibility of the algorithm in passive radar application.
