摘　　要：在现代海战中,随着雷达分辨率的提高及信号带宽的增加,雷达海杂波越来越复杂,建立准确而有效的雷达海杂波模型,对雷达电子战系统的仿真具有重要意义。常见的海杂波模型有瑞利(Rayleigh)分布、韦布尔(Weibull)分布、对数正态(Log-Nornal)分布、K分布等,这些分布有其各自不同的应用环境与优缺点。而广义复合(Generalized Compound)分布模型具有较强的灵活性,适于高分辨雷达的杂波建模。分析广义复合分布模型及其原理,并采用零记忆非线性变换(ZMNL)法仿真相关广义复合分布杂波,从而验证了算法的有效性及模型的实用性。In the modern naval warfare, with the increasing of radar＇ s resolution and signal＇ s bandwidth, the sea clutter has become more and more complicated. It＇ s very important to establish an accurate and efficient radar model of sea clutter for the radar electronic warfare system. The common sea clutter models are based on the Rayleigh distribution, Weibufl distribution, Log-Normal distribution and K distribution. Different distribution models have their own application situations, advantages and disadvantages. The Generalized Compound distribution model has relatively strong flexibility, which is suitable for the modeling of high resolution radar clutter. The model and principle of Generalized Compound distribution are analyzed. The correlated Generalized Compound distribution clutter is simulated with the Zero Memory Nonlinearity （ZMNL） method,by which the effectiveness of the algorithm and the practicality of the model are verified.
