摘　　要：为提高机载平台对隐身目标的探测能力,提出一种基于地球同步轨道合成孔径雷达(GEO SAR)辐射、多个机载平台接收的多基雷达协同探测系统,该系统具有覆盖范围广、机载射频隐身、生存能力强等优势。分析了星机协同的作战优势,可获取目标RCS空间闪烁增益、双基RCS增益以及融合增益。分析了星机双基协同探测威力与多基融合探测威力,可提高隐身目标探测距离。通过仿真实验验证了分析的有效性。To improve the detection performance of stealth targets in the airborne system,a multistatic radar system with a transmitted Geosynchronous synthetic aperture radar(GEO SAR)and multiple received airborne platforms is proposed,which has the advantages of broad coverage,airborne radio frequency stealth and high survivability.Firstly,the operational advantages of system are analysed,which can obtain target’s RCS spatial variation gain,bistatic RCS gain and fusion gain.Secondly,the detection performance of bistatic radars and the fusion detection performance of multistatic radars are studied,which can improve the detection range of stealth targets.Finally,the effectiveness of the analysis is verified by simulation experiments.
