摘　　要：针对双基地雷达辐射源和接收站与地物杂波存在的相对运动,导致雷达配置场景下出现的杂波复杂化问题,提出非合作辐射源雷达杂波建模方法。该方法构建了非合作运动雷达辐射源及固定地面接收站体制下的杂波谱,并对其杂波分布的影响进行了理论分析和仿真研究。仿真结果表明:杂波特性会随着距离的增大而愈加平稳;不同配置下,杂波自由度愈大,杂波谱的复杂度也愈大。非合作辐射源雷达杂波建模方法扩展了杂波模型适用范围,简化了计算,为非合作辐射源雷达的杂波抑制与目标检测奠定了基础。Aiming at the relative motion of bistatic radar emitter and receiver station with ground object clutter,which led to the complexity of clutter in radar configuration scenario,a non-cooperative emitter radar modeling method was proposed.This method constructed the clutter spectrum for the non-cooperative motion radar emitter and the fixed ground receiving station system,and carried on the theoretical analysis and the simulation research on the influence of the clutter distribution.The simulation results showed that the clutter characteristics would become more stable with the distance increase;under different configurations,the greater the clutter degree of freedom was,the greater the complexity of clutter spectrum would be.The clutter modeling method of non-cooperative emitter radar expanded the application scope of clutter model and simplified the calculation,which set a foundation for clutter suppression and target detection of non cooperative emitter radar.
