摘　　要：本文采用零记忆非线性变换法和球不变随机过程法对海杂波进行了建模和仿真研究,实现了相参Rayleigh分布、相参Weibull分布和相参K分布杂波的模拟,并对建模和仿真数据进行了检验,验证了建模和仿真方法的有效性。本次建模的特色之处在于考虑了杂波的相参性,并建立了三种杂波的概率分布模型和功率谱模型。This paper researches sea clutter modeling from two aspects： zero memory nonlinearity, spherically invariant random process. First, coherent Rayleigh, coherent Weibull and Coherent K clutter are simulated with zero memory nonlinearity transform and spherically invariant random process, and the accuracy of these model compared with the theories is verified in the thesis. Considering the relativity of sea clutter and building up three model of power spectrum density and PDF are the features of this thesis.
