摘要
分析了目前常用的杂波建模方法，阐述了最大熵分布的重要作用，提出了一种杂波幅度的统计建模方法，通过提取实测杂波数据的中心矩来对杂波幅度的随机特性进行描述，并通过模拟退火算法对杂波数据进行仿真。最后利用McMaster大学IPIX雷达的一组实测海杂波数据对算法进行了验证，结果表明，仿真数据与实测数据的最大熵分布具有很高的拟合程度。
The clutter modeling methods are analyzed, and the importance of maximum distribution is illustrated. A modeling method is introduced then,which uses the central moment information of measured data to describe the statistical character of radar clutter,and then the simulated an- nealing（SA）algorithm is used to simulate the radar clutter data. Lastly,a set of measured clutter data of IPIX radar,which is published by McMaster University,is used to exemplify introduced,and the result indicates that the simulated data has a good fitness with th distribution of measured clutter data.
