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所广泛采用的杂波模型。文中在总结SIRP主要理论结果的基础上,详细分析了参考文献[7]中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。
Spherically invariant random process（SIRP） is commonly used in simulating of high-resolution radar clutter. This paper summarizes main theoretical results of SIRP. An inefficient simulation method which is applied to heavy tailed spiky clutter and given in reference[7] is thoroughly probed. A simulation scheme is proposed which 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 imorove the simulation efficiency remarkably.
