摘要
为了研究L波段小擦地角海杂波幅度统计特性及其在不同海洋参数条件下的差异,该文结合海杂波实测数据,选取适当的拟合优度检验准则,对比分析给出了不同波高和风向条件下Rayleigh,Weibull,Log-normal,K分布等经典统计分布模型,以及典型参数条件下Pareto分布在L波段小擦地角海杂波建模中的拟合效果,可为雷达目标检测中杂波模型的选择提供参考,提高海洋环境背景下目标检测的适应能力。
In order to investigate amplitude statistics and variation under different ocean parameters of L-band low grazing angle sea clutter, in this paper, based on the L band real sea clutter data collected in different wave height and wind direction and proper goodness of fit rules, fitting result of Rayleigh, Weibull, Log-normal, K-distribution and Pareto distribution in modeling low grazing angle data are compared. The applicability of the above models are discussed. It can provide reference for the selection of clutter model in radar target detection, improve the adaptability under maritime environment of target detection.
