摘　　要：准确而有效地模拟雷达杂波信号,对于机载PD雷达的目标检测具有重要意义。提出一种基于统计模型的ZMNL法对杂波仿真,阐述了该方法的思路和实现步骤,给出实现模型和仿真结果。计算机仿真的结果证明,用该方法来描述雷达杂波的"长拖尾"是合理的,为机载PD雷达检测提供了依据。It has important significance of simulating radar clutter signal accurately and effectively for target detection process of airborne pulse Doppler（PD） radar.The method of zero memory nonlinearity（ZMNL） for clutter simulation based on clutter＇s statistic model is presented,the scheme and implementation procedure of this method are illustrated,and the implementation model and simulation results are given.The computer simulation results can prove that it is reasonable of using this method to describe the long hangover of correlation radar clutter.It provides a basis for target detection of airborne PD radar.
