摘　　要：针对机载脉冲多普勒(PD)雷达地杂波仿真实现的复杂性,基于一种简化的机载PD雷达相干地杂波仿真模型,建立了机载PD雷达在地杂波中检测目标的模型。该方法能准确反映出高度线杂波、主瓣杂波、副瓣杂波、目标回波的功率关系。结合仿真结果分析了机载PD雷达对处于不同杂波区目标的检测能力,结果与实际情况符合较好。Aiming at the complexity to realize ground clutter simulation of airborne pulse Doppler（PD）radar,this paper builds up the model of airborne PD radar detecting targets in ground clutter based on a simplified coherent ground clutter simulation model of airborne PD radar.The method can accurately reflect the power relations among height clutter,main-lobe clutter,side-lobe clutter and target echo.Combined with simulation result,the target detection capability of airborne PD radar in different clutter zones is analyzed,and the result is consistent with practice.
