部分截取雷达信号多假目标干扰性能分析

分析了部分截取雷达信号多假目标干扰原理。分析得出经过雷达信号处理后其存在功率损失,计算出了其功率损失与截取比例的关系,同时通过仿真得出了其信号在进行雷达脉压加窗处理后将带来的加窗损失。分析了部分截取雷达信号多假目标干扰信号由于与雷达匹配滤波器失配带来的额外信噪比损失,并计算得出了其信噪比损失与截取比例的关系。分析了部分截取雷达信号多假目标干扰的功率损失和信噪比损失对干扰效果的影响。最后,将部分截取雷达信号多假目标压制干扰与时域叠加多假目标压制干扰的性能进行了比较。

The Performance Analysis of Multi-False Targets Jamming of Part Copying Radar Pulse

The principle of multi-false targets jamming by part copying radar pulse is analyzed.The power loss of the jamming single is pointed out after radar single process,the relation of the power loss and the copying proportion of radar pulse is arrived,and the power loss after the pulse compress with hamming window is obtained.The SNR of part copied radar pulse and radar single is calculated,and the formula of the SNR loss and the copying proportion of radar pulse are given out.The power loss of multi-false targets jamming by part copying radar pulse and its effect to jamming influence are analyzed.At last,the jamming performance of multi-false targets jamming by part copying radar pulse is compared with multi-false targets jamming by superposition of the radar signal.
