摘　　要：针对无源雷达系统探测空域,研究了无源雷达系统单站探测远界与低界模型,并建立了组网探测空间模型。针对无源雷达系统定位能力,分析了三维空间时差定位方法,及三维空间时差定位精度。以机载电子干扰系统为探测目标,通过定量方法分别对无源雷达系统探测及定位能力进行了仿真分析。仿真分析表明:研究的相关方法与结论,对明确未来无源雷达系统需求、指导无源雷达系统的部署与使用等方面具有意义。As to the detecting area,the single station detecting far range and low range model is proposed,and the detecting space of the network radar is studied based on that.As to the locating capability,a 3-D space time-difference-of-arrival（TDOA） position system is introduced,and the geometric dilution of precision of the system is analyzed.Taking the jamming aircraft as the typical target of passive radar,the detecting and the locating ability of the passive radar is simulated and analyzed separately by quantitative method.The referred methods above and the conclusions are meaningful to ascertaining the future requirement and the deployment and the application of the passive radar system.
