中文摘要：

首先提出了一个单发多收的无源雷达成像系统,并给出了该系统的时域算法.然后针对所需接收机较多、系统过于复杂的问题,又提出一种多发多收的成像系统,并给出了其处理算法.多发多收系统的复杂度大大降低,其分辨率更佳,副瓣也被充分抑制.在理论分析基础上,多发多收系统取得较好的仿真结果,验证了所提系统和算法的有效性.

英文摘要：

This paper firstly proposes a single external illuminator multiple receivers passive radar imagingsystem , and presents the time-domain algorithm for this system. M oreover, as for the problem that thenumber of receivers needed by the proposed system is large, and the proposed system is rather complicated,a multiple illuminators multiple receivers imaging system is illustrated, and its processing algorithm is alsopresented. For this system , the complexity is reduced greatly, its resolution is rather high, the sidelobe isfully suppressed. Based on the theoretical an alysis, multiple illuminators multiple receivers imaging systemcan achieve rather good simulation results, and then the effectiveness of the system and algorithm is verified.
