摘　　要：针对国防工程口部防星载SAR侦察伪装防护问题,系统研究了星载SAR对工程口部的可探测性威胁。首先,基于空间目标运行理论建立星载SAR轨道模型,分析典型星载SAR卫星的轨道特点;其次,根据SAR成像模式推导星载SAR雷达波束相对于工程口部的视向角模型,获得方位向和俯仰向2个角度的解析表达式;最后,以国外典型星载SAR为典型案例,仿真分析卫星对国防工程的重点威胁方向,为工程口部选址以及防雷达伪装设计提供依据。In view of the problem of the defense engineering gateway camouflage and protection against reconnaissance by space-borne synthetic aperture radar(SAR),this paper systematically studied and analyzed the detectability threats from space-borne SAR.Firstly,a space-borne SAR orbit model was built based on space target operation theory,and the typical characteristics of space-borne SAR orbit was analyzed;Secondly,the visual angle model of space-borne SAR beam relative to the gateway of defense engineering was derived from the SAR imaging modes,and the analytical expressions of azimuth angle and pitch angle were obtained.Finally,taking typical foreign space-borne SAR as example,the main threats from satellite to the defense engineering were simulated and analyzed.The research conclusions of this paper could be used as a reference for site selection and design of camouflage protection against radar reconnaissance of the defense engineering gateway.
