摘　　要：伪码调相连续波(PRC-CW)雷达在实际工作中存在分辨单元叠加和距离门外目标相关泄漏现象.从相关信号处理的角度对杂波回波进行了分析,并以某型雷达实测数据为例,研究了PRC-CW雷达的杂波特性.分析表明,在叠加效应下杂波的幅度特性分布出现了展宽,空间相关性增强,但时间相关性变化不显著.In the actual use of PRC-CW radar,there exist superposition of resolution element and leakage of signal outside of range gate.In this paper,the clutter echo is analyzed based on related signal processing theory.In the case of the data of a certain type of PRC-CW radar,the feature of land clutter is studied and analyzed.The measured data shows that the clutter echo amplitude distribution is spread and temporal correlation enhanced,but the change of spatial correlation is not obvious.
