摘　　要：相关K分布是一种适于描述雷达海杂波的非高斯分布模型。快速、准确地模拟雷达海杂波,对雷达最优信号处理器的设计及雷达系统的模拟是十分重要的。讨论了相关K分布海杂波的建模与仿真,在K分布的自相关函数与高斯分布的自相关函数之间的非线性关系的基础上,利用修正的零记忆非线性变换(ZMNL),仿真产生了相关复合K分布雷达海杂波。仿真实验结果表明,这种方法是准确、有效、可行的。Radar sea clutter can be statistically modeled by using a non-gaussian probability density function of correlated compound K-distributed.It is important to rapidly and correctly simulate radar sea clutter for the design of radar optimal signal processor and the simulation of radar system.Modeling and simulation of correlated K-distributed sea clutter are discussed in this paper.The correlated compound K-distributed radar sea clutter is generated by modifying zero memory nonlinearity(ZMNL)on the base of the autocorrelated function nonlinearity relation between K-distributed and gaussian.Simulated results show that the scheme is correct,valid and feasible.
