基于AR模型和ZMNL变换的K分布海杂波仿真方法

摘要

海杂波统计模型的研究对最优检测算法设计和雷达性能预估有重要作用.文章介绍了一种基于AR模型和ZMNL变换的K分布海杂波仿真方法,结合ACI准则和Yule-Walker方程,利用Levinson-Durbin递推关系式求解AR模型的阶数和参数,将生成的高斯序列通过线性滤波器产生服从K分布的相关序列.仿真结果表明,无论是功率谱还是概率分布都与理想分布相吻合.%The research on sea model is of great significance for optimum detection algorithm design and performance prediction. A simulation method for the K Clutter based on AR module and ZMNL transform is proposed. The method solve the step and parameters using Levinson-Durbin combined with ACI rule and Yule-Walker equation, and produce the K clutter serial by sending the gauss serials into linear filter. Simulation results show that both PSD and PDF are in accord with perfect distribution.
