摘　　要：建立了基于单频网的数字电视广播辐射源雷达目标探测模型,分析了单频网外辐射源雷达存在的特殊问题及措施,提出了基于航迹关联和航迹同源映射的单频网外辐射源雷达目标定位算法,解决了由多个同频发射信号引起的目标定位模糊问题。由一个三发单收的单频网外辐射源雷达模型验证所提算法,仿真结果表明该算法有效地消除定位模糊。A target detection model for DTTB-based passive radar in a single frequency network （SFN） is established. Also, the distinctive difficulties of the SFN passive radar is analyzed, and the target location algorithm based on the track mapping and the track association to eliminate the location ambiguity caused by many transmitters of the SFN passive radar is proposed. A SFN passive radar composed by three transmitters and one receiver is used to verify the algorithm. The simulation results show that the algorithm can eliminate the location ambiguity and increase the location accuracy effectively.
