摘　　要：文中描述了被动雷达功能仿真的主要过程,设计了被动雷达功能仿真平台。在此基础上,文中针对噪声调频干扰信号进行建模,进一步模拟了被动雷达系统对噪声调频干扰信号的跟踪过程。通过对仿真结果进行分析,文中证实了测量的到达角与真实值存在一定的偏差;当噪声调频干扰源在一定带宽范围内时,采用跟踪到达角平均值的方法可以使被动雷达导引头成功地搜索到目标。The whole simulating process of the passive radar function was described in detail. A simulation system was constructed within which each component model was built up. Moreover, the noise FM jamming signal of aimed wideband jamming was well discussed. The experimental results show the paper verifies that there are errors between the DOA and its real value, which is coincident to the realities. Moreover, it is proved that when the noise FM jamming source falls in certain range, the method of the average of DOA can make seeker catch target successfully.
