摘　　要：雷达杂波的仿真是进行雷达性能评估的重要手段,也是雷达信号处理的一种重要课题。球不变随机过程(SIRP)是雷达杂波建模的主要方法之一,SIRP可以用来描述雷达杂波的幅度统计特性和时间相关特性,这是因为SIRP的幅度概率密度函数和协方差矩阵可以独立控制。在讨论SIRP的基本性质的前提下,分别针对CHI分布和K分布,给出了两种基于SIRP的相关雷达杂波仿真的方法。最后利用计算机仿真对雷达杂波的幅度概率分布和相关性进行了验证,证明了该方法的有效性。Simulation of the radar clutter is the most important method to evaluate tbe radar perform ance, and is also the important subject of the radar signal processing. The spherically invariant random proeesses（SIRP） is one of the major methods to model the radar clutter, and is used to describe the amplitude probability function and correlation function of radar clutter, and the amplitude probability function and correlation function of SIRP can be controlled independently. In this paper, the basic characteristic of SIRP is discussed at first, and the two kinds of radar clutter simulation methods based on SIRP are given, for CHI distribution and K distribution respectively. The computer simulation is used to validate the amplitude proba bility function and correlation function of simulated radar clutter.
