摘　　要：雷达散射截面(RCS,Radar Cross Section)用于表征雷达目标对照射电磁波反射特性,在被动雷达系统中,雷达散射截面是判断能否检测到目标的一个重要参数。针对以广播电视卫星为外辐射源的被动雷达系统对海面目标进行检测的问题,仿真了目标和海面的双基地雷达散射截面(RCS),分析外辐射源-仿真对象-接收机位置关系对雷达散射截面(RCS)的影响,讨论了目标和海面的雷达散射截面(RCS)与角度的关系,对被动雷达系统如何选择外辐射源具有一定参考价值。Radar cross section(RCS)is used to characterize the reflection characteristics of radar target to irradiated electromagnetic waves,in passive radar system,radar scattering section is an important parameter to judge whether the target can be detected,aiming at the problem of passive radar system with radio and television satellites as the external radiation source to detect sea surface targets,this paper simulates the bistatic radar scattering section(RCS)of the target and sea surface,and analyzes the external radiation source-simulation object-the influence of receiver position relationship on radar scattering cross-section(RCS),and the relationship between radar scattering cross-section(RCS)and angle of target and sea surface are discussed.

关 键 词：外辐射源 广播电视卫星 RCS
