功率角度的密集假目标压制干扰分析

Analysis to Blanket Jamming Effect of Dense Deceptive Targets Based on Power

以分析密集假目标的压制干扰效果为目的,提出了一种提高密集假目标干扰效果的干扰方法。首先研究了线性调频信号的间歇采样多假目标经过脉冲压缩后的功率分布,然后分析了密集假目标压制干扰对CA-CFAR检测的影响,最后根据研究的功率分布结果,通过调整相关参数使密集假目标的压制干扰效果最优。结果表明,该方法能大大提高干扰效果。

For the purpose of analyzing the blanket jamming effect of the dense deceptive targets,a new jamming method for improving the jamming effect of the dense deceptive targets is proposed.Power distribution of multiple deceptive targets after pulse compression,generated by intermittent sampling of Linear Frequency Modulation（LFM） radar signals,is analyzed firstly.Then,the influence of dense deceptive targets jamming on radar detection of CA-CFAR is analyzed.The ideal jamming effect is achieved by adjusting related jamming parameters based on power distribution of multiple deceptive targets.The simulation results show that this method can improve the jamming effect greatly.
