摘　　要：对K分布海杂波的建模与仿真进行了研究,给出了一种基于零记忆非线性变换的K分布海杂波序列产生方法和步骤,首先产生相关的高斯随机过程,然后经过某种非线性变换得到所求的相关随机序列。在滤波器的设计中,通过引入粒子群优化算法对参数进行了优化,以达到更好的效果。最后仿真产生了相关K分布的雷达海杂波,结果表明该方法是有效的。Modeling and simulation of correlated K-distributed sea clutter are discussed.It gives the simulation process to generated K-distributed clutter based on zero memory nonlinearity（ZMNL）.At first it generates correlated Gauss sequence and then generates correlated stochastic sequence by some nonlinearity transform.The correlated K-distributed radar sea clutter is generated by ZMNL in the end.PSO（particle swarm optimization） is applied to the parameter optimization so as to get more satisfactory clutter simulation.Simulation results show that the concept is correct and feasible.

关 键 词：相关K分布 雷达海杂波 零记忆非线性变换 粒子群优化算法
