相参相关雷达杂波的建模与仿真

ZMNL法和SIRP法是目前最常用的两种杂波模拟方法，文中对这两种方法分别作了简要的介绍，并且详细讨论了基于以上两种方法的Rayleigh，Log Normal，Weibull分布和K分布杂波的产生原理和仿真流程。随后用ZMNL法对高斯谱Rayleigh分布和Log Normal分布杂波进行了仿真，同时分别用ZMNL法和SIRP法对基于相参脉冲雷达杂波模型的Weibull分布杂波和K分布杂波也作了仿真。最后，对所产生的杂波作了功率谱估计。实验结果证明，以上两种方法是有效可靠的。

Modeling and Simulation of Coherent Correlated Radar Clutter

Zero Memory Nonlinearity(ZMNL) transform and Spherically Invariant Random Process(SIRP) are two kinds of simulation methods of radar clutter used frequently at present. A brief introduction of the two methods is given in this paper. Based on the two methods, the principle and flow of simulation of Rayleigh, Log Normal, Weibull and K-distributed clutters are discussed in detail. Subsequently, Rayleigh and Log Normal-distributed clutters based on Gaussian spectrum are simulated with ZMNL, and Weibull and K-distributed clutters based on coherent pulsed radar clutter model are also simulated with ZMNL and SIRP respectively. Finally, some power spectrum methods are used to analyze the clutter data. The validity of the methods is proved by simulated results.
