摘要
基于速度波门拖引干扰的信号模型,提出了一种基于小波分解的抗速度波门拖引干扰的方法.通过对目标多普勒回波信号进行小波分解,选取适当的阈值,滤除波门拖引的调频部分,并对回波信号进行小波重构修正,得到消除干扰的回波信号,由此进行运动目标跟踪检测.仿真结果表明,此方法是可行的.
Based on the velocity gate walkoffjamming signal model, a method of anti-VGWO jamming was proposed in terms of wavelet decomposition. By way of wavelet decomposition of target Doppler returns, selecting the proper threshold, filtering the FM portion of gate walkoff and doing wavelet reconstruction and correction, the returns with eliminated jamming were obtained, by which, the moving target tracking and detecting was done. The simulation result shows that this method is feasible.
