【摘要】 首先介绍基于民用照射源的被动雷达应用概况,给出了系统配置示意图,分析了调频广播信号作为雷达照射源的模糊函数和目标检测的二维相关算法。针对运算量巨大的问题,重点介绍了改进的二维相关算法,减少了运算量。简单介绍基于流水线结构的多DSP信号处理机,以实时完成信号检测与估计任务。更多还原

【Abstract】 Firstly the application of the civil illuminators based passive radar and its system configuration are introduced. The ambiguity function of the FM radio signal as a radar illuminator and the 2-D correlation algorithm in target detection are analyzed. Aiming at the huge computation complexity problem, the improved arithmetic empathically is given. A schematic diagram of the signal processor is also proposed.更多还原
