摘　　要：广义K分布(GK-pdf)模型,是一种适用于宽带雷达杂波仿真的分布模型。文中首先研究了广义K分布模型及其统计特性,得到了相关系数之间的非线性关系。从而利用零记忆非线性变换(ZMNL)方法仿真了相关广义K分布杂波,给出了基于ZMNL法的相关广义K分布杂波序列仿真原理和算法流程图,并仿真了几种经典的特殊广义K分布。仿真结果表明了该方法的有效性、准确性。The generalized K probability density function（GK-pdf） is one of the distribution model for simulation of wide band radar clutter.This paper discusses the GK model and its statistical properties and obtains the nonlinear connection.Then correlated GK distribution clutter is simulated using ZMNL method.The method using ZMNL to generate correlated GK distribution clutter sequence and its flow chart is presented,and several classic special GK distribution are generated.Simulated results show that the concept is valid and correct.
