| 摘 要： | 球不变随机过程（SIRP）是对高分辨率雷达的检测性能进行仿真分析时广泛采用的杂波模型。在总结SIRP主要理论结果的基础上，详细分析了Rangaswamy M等学者给出的仿真方法对长“拖尾”的“尖”杂波仿真效率低的原因，提出了对杂波包络的概率密度函数（PDF）进行分割，用分割点上的PDF值来构造上界函数的新的仿真方法，仿真算例表明改进的方法显著地提高了仿真的效率。

| Abstract: | Spherically invariant random process(SIRP) is commonly used model in simulating high-resolution radar clutter.This paper summarizes main theoretical results of SIRP.Inefficient simulation method when applied to long tailed spiky clutter used is thoroughly analyzed.The proposed new simulation scheme is based on segmentation of envelope PDF of the radar clutter to form upper bound of this PDF.Examples show that the new method can improve efficiency significantly. |
