摘要: 针对多假目标干扰对恒虚警（CFAR）检测雷达的干扰效果评估问题,根据CFAR检测原理,分析了多假目标干扰下雷达CFAR检测门限和不同间隔的多假目标的干扰效果,得到了在一定密度和功率的多假目标干扰下,部分雷达将出现无任何信号输出的自压制状态的结论,最后通过仿真进行了验证,研究可以用于指导多假目标干扰的设计。Abstract: For the effect evaluation problem of the multi-false-target jamming against constant false-alarm rate（CFAR） detection radar, the detection threshold of CFAR detection in multi-false-target jamming was studied according to the principle of the CFAR detection, and the jamming effect of the multiple false targets with different interval was analyzed. The conclusion is that the radar with CFAR detection method will output no signal by the effect of the multi-false-target jamming with stated power and density in the specific false alarm probability. At last the simulation was done to prove the analysis. The research can be used to design the multi-false-target jamming.
