基于盲源分离的抗密集假目标干扰技术研究

Study of Dense False Targets Anti-jamming Technology Based on Blind Source Separation

密集假目标干扰会严重影响雷达检测目标的性能。针对此问题,提出一种基于盲源分离的密集假目标抗干扰的方法。该方法可有效从密集欺骗式假目标中检测出目标回波信号,并分析比较了JADE和Fast ICA两种盲源分离方法对密集欺骗式假目标和回波信号的分离效果。理论分析和仿真结果表明:JADE盲源分离较Fast ICA盲源分离抗密集假目标干扰较更有效。

Dense false target jamming will seriously affect the detection performance of radar.Aiming at this problem,a new method of dense false targets anti-jamming technology based on blindsource separation is proposed.This method can effectively detect the target from the dense false targetecho signal and analyze the dense false target and echo signal separation effect of two kinds of JADEand Fast ICA blind source separation method.Simulation results show:JADE blind source separation ismore effective of dense false target anti-jamming than Fast ICA blind source separation.
