摘　　要：在现代雷达体制中,广义复合分布模型更适用于描述雷达海杂波的幅度分布特性。在海杂波的仿真中,准确、高效地模拟海杂波,对雷达信号处理和海面目标检测具有重要的现实意义。文中讨论了广义复合分布海杂波模型,提出一种基于零记忆非线性变换的相关广义复合分布海杂波仿真的新算法,该新算法采用独立产生杂波序列的幅度与相位的方法,可以避免求解复杂的非线性方程,具有运算量小的特点。仿真实验结果表明了该方法的准确性和可行性。The generalized compound distribution model is more suitable to describe the amplitude distribution characteristics of ra- dar sea clutter. It is practically significant to simulate radar sea clutter accurately and efficiently for radar signal processing and sea target detection. Modeling of coherent correlated generalized-compound distribution was discussed. Then a new algorithm to simu- late coherent correlated generalized compound distribution which was based on Zero Memory Nonlinear Translation was proposed. The algorithm generated the amplitude and phase of the distribution independently, which avoided solving the complex nonlinear equations and had smaller computation. The simulation results showed the validity and feasibility of this method.
