摘要
在分析典型地物杂波的空间分布特性的基础上，针对ＰＲＣ－ＣＷ（伪码调相连续波）雷达的特性，即雷达在低俯视角情形时地面回波信号展宽，利用对码元回波复信号进行空间矢量叠加以得到ＰＲＣ－ＣＷ雷达实际接收的回波信号．通过计算机模拟得到伪码调相连续波雷达回波信号后，对其空间相关特性进行了分析．
Based on the previous results on the spatial correlation characteristics of some typical land clutter, and in accordance with the specialty of pseudo random code CW (PRC -CW) radar, i.e., the time spread of echo signal under the condition of low grazing angle, a superposition algorithm was used to get real clutter echo of PRC -CW radar. The correlation characteristics of land clutter for PRC -CW radar was investigated with simulation method.
