摘要
为改善舰载雷达目标检测的性能,对瑞利分布、对数正态分布、韦布尔分布和K分布四种典型海杂波幅度分布模型进行模拟仿真,分析了四种分布模型的特点规律,并采用海杂波实测数据,对模型进行拟合度检验,实验结果表明,K分布海杂波模型实用性广,能够在不同参数下描述多种海况的海杂波分布规律,为抑制海杂波提高目标检测性能提供了理论依据。
In order to improve the performance of shipborne radar target detection,four typical sea clutter amplitude distribu-tion models,such as Rayleigh distribution,logarithmic normal distribution,Weibull distribution and K distribution,are simulat-ed,and the characteristics of the four distribution models are analyzed.By using the measured data of sea clutter,the model is test-ed for fit degree.The experimental results show that the model of sea clutter with K distribution is practical and can describe the law of sea clutter distribution in various sea conditions under different parameters.It provides a theoretical basis for suppressing sea clut-ter and improving target detection performance.
