摘　　要：为解决海杂波模型过于简单、逼真度不高及杂波模拟缺乏针对性等问题,提出一种基于实测数据的海杂 波建模方法。在分析经典海杂波统计模型基础上,利用导引头采集不同海况下的实测数据,采用拟合度检验及参数 估计的方法,结合SIRP法模拟生成仿真杂波数据,通过对经典统计模型进行修正,得到实用的海杂模型。仿真结果 表明,该方法对于提高射频仿真系统中海杂波模型逼真度及置信度具有参考价值。In order to solve the problems of sea clutter modeling such as simplicity,low fidelity,and lack of pertinence,a sea clutter modeling method based on measured data is proposed.Based on the analysis of the classical sea clutter statistical model,the seeker is used to collect the measured data under different sea conditions,and the simulation clutter data are generated by fitting test and parameter estimation and combined with SIRP method.The practical sea clutter model is obtained by modifying the classical statistical model.The simulation results show that this method has reference value for improving the fidelity and confidence of sea clutter model in radio frequency simulation system.
