K分布海杂波参数估计方法研究

Parameter Estimation Study of K-distributed Sea Clutter

K分布模型在雷达杂波分析、建模、仿真及雷达目标检测中有着广泛应用,因此K分布杂波的参数估计方法非常重要。已有的K分布杂波的参数估计方法较多,然而在实际应用中缺乏从众多估计方法中选择合适方法的标准。本文针对常见的几类k分布参数估计方法,通过计算机仿真进行性能分析和比较,得出不同条件下选择参数估计方法的基本原则,并且将其应用于实际的海杂波数据建模分析中,从而对工程实践起到了指导作用。

K-distribution PDF is an important model in clutter analysis,modeling, simulation and radar target detection. It＇ s parameter estimation method has been studied widely and deeply,but there is no guidence to choose the better one from many estimation methods in practice. In this paper,we analysis and compare the performance of several parameter estimation method,give the basic guide lines for choose good estimator under different conditions. It has been used to modeling the measured sea clutter and the tests give good results.
