本文首先论述了伪码调相连续波雷达的特殊性，然后分析了一些典型地物杂波的统计特性，在此基础上，针对伪码调相连续波雷达在低俯视角情形时回波信号展宽的问题，提出了对码元回波幅度进行空间矢量迭加以得到实际回波信号的方法，通过计算机模拟，得到了迭加时实际回波的概率密度分布模型．
In this paper, firstly, the particularity of Pseudo Code Phase Modulated Continuous Wave Radar is discussed. Then, the statistical characteristics of some typical clutter are analyzed. Based on the above analysis, for the case of Pseudorandom Code Modulated Continuous Wave Radar This paper proposes a method of space vector superposition of the amplitude of the symbol echo to obtain the actual echo signal. By computer simulation, the probability density distribution model of the actual echo during superposition is obtained.
