摘　　要：杂波在雷达环境模拟中具有非常重要的地位。基于ZMNL(无记忆非线性变换法)的Weibull分布雷达杂波模型,可以很好地描述海杂波。但这种模型,因其非线性变换前后相关系数之间的关系公式复杂,很难用直观的方法求解。针对这一问题,提出了用迭代算法来求解该非线性公式的过程,并给出了应用该方法进行杂波仿真的具体步骤及仿真结果,证明了该方法的准确、可行性。Abstract：Radar clutter plays an important part in the simulation of radar environment. The Weibull- distribution radar clutter model which is based on ZMNL can well describe the sea clutter. But in the model, the formulas which describe the relation between the correlation coefficients before and after the nonlinear transform is complex and difficult to be solved with visualized method. For this problem, an interative algorithm which is to calculate the nonlinear formulas is proposed. The application process of this method in clutter simulation is described. The results prove that the method is aceutrate and feasible.
