摘　　要：针对主动雷达测向方法存在的弊端,提出一种基于单频连续波外辐射源信号的被动雷达测向方法.首先给出了一种被动雷达测向系统,然后提出了相应的时域测向算法并得到了其角度分辨率、峰值旁瓣比,最后进行了仿真.仿真结果表明,所得的角度分辨率和峰值旁瓣比是正确的;本文方法能够准确地对随机出现的目标进行测向,验证了所提算法的有效性.In view of the disadvantages of the active radar direction finding method, this paper presents a method for passive radar direction-finding based on the external illuminator signals of single frequency continuous wave. At first, a sort of passive radar direction finding system is introduced, and then the corresponding time domain direction finding algorithm is proposed for obtaining the angle resolution and the peak side lobe ratio, and finally, the simulation is performed in this paper. Simulation results show that the obtained angle resolution and the peak side lobe ratio are accurate, and this proposed method can be used for the direction finding of random targets, which proves the algorithm to be of effectiveness.
