摘　　要：当目标被大时间带宽积的信号照射后，其回波特性并不呈现出点目标特性。对于这种目标回波信号的检测可以利用相关滤波的方法。本文将叙述相关滤波法的原理和性能。由于采用此法可以提高目标信号／噪声比，因而也可使低ＲＣＳ（雷达反射截面积）目标检测性能得到提高。When a target is illuminated by a radar LFM(Linear Frequence Modulation)pulse,and the backscattered power is recorded as a function of time.The method of improvement detection performance the target with High-Range-Resolution radar is a correlation filter.In this paper,the correlation filter for detection target is investigated. The results suggest that this method can improve the detection performance of low RCS target.
