Near-space passive coherent location system based on remote early warning radar

针对空中高价值隐身目标的探测问题,研究了基于远程预警雷达的临近空间无源相干定位技术。对目标探测距离进行了简单分析计算,给出了系统工作信号处理流程,对其中的主要关键技术进行了梳理。该技术可应用于无线电静默状态下的非协同探测定位系统项目,通过与电子侦察系统多传感器融合可以进一步完善防空体系无源探测网,完成对侦察目标在电子静默情况下的态势判断。

To solve the problem of target detection for high-value stealth targets in the air, near space passive coherent location technique based on remote early warning radar is researched. Simple analysis and cal-culation of target detection distance is carried out. The signal processing flow of the system is given, and the key technologies are sorted out. The technique can be applied to non cooperative detection and location system project in radio silence. Passive detection network of prevention and control system can be more perfect through fusing with electronic reconnaissance system＇s multi-sensor in order to complete the situation estimation of the target in the case of electronic silence.
