摘　　要：雷达杂波仿真是雷达研究的一项关键技术,本文首先深入研究了几种经典杂波模型的统计特性;在此基础上,引入最小相位特性与复倒谱技术,给出了一种物理可实现的滤波器产生方法,同时详细阐述了物理可实现经典杂波随机序列产生的流程;最后,进行了仿真实验,仿真结果证明了该方法的准确性和有效性。该方法产生的杂波信号可用于雷达信号模拟、雷达图像分析及雷达最优信号处理器的设计。It is one of the key techniques in the radar research for the radar clutter simulation,firstly,this paper studies statistics characteristic of the classic clutter models and simulation method of ZMNL （Zero Memory Nonlinearity）. Then adopting minimum phase feature and complex cepstrum technology, this paper educes the technique of the realizable filter in physics. Then the method of generation of general random clutters sequences is set forth profoundly. Finally, the simulation is processed and the results prove the validity and veracity of the method proposed in this paper. The clutters generated by this method can be used in the simulation of radar signal, analysis of radar image and optimization of radar signal processor.
