外辐射源雷达的研究和应用正朝着由单收发对向多收发对体制发展。作为该型雷达的一种重要机会照射源，新一代数字广播电视广泛采用单频(或同频)网覆盖方式，其内在决定了基于此的外辐射源雷达是分布式和网络化的。鉴于照射源单频网配置下外辐射源雷达不同寻常的工作和处理方式，该文归纳提出了单频网分布式外辐射源雷达的概念，阐述了该型雷达的主要特性以及所面临的核心问题，并就部分关键技术讨论了若干可供尝试的解决方案，结合原理实验结果展示了该型雷达的可行性，最后提出了集外辐射源雷达探测网的四网融合的概念并展望了其应用前景。

The research and application of passive radar are heading from single transmitter-receiver pair to multiple transmitter-receiver pairs. As an important class of the illuminators of opportunity, most of modern digital broadcasting and television systems work on Single Frequency Network (SFN), which intrinsically determines that the passive radar based on such illuminators must be distributed and networked. In consideration of the remarkable working and processing mode of passive radar under SFN configuration, this paper proposes the concept of SFN-based Distributed Passive Radar (SDPR). The main characteristics and key problems of SDPR are first described. Then several potential solutions are discussed for part of the key technologies. The feasibility of SDPR is demonstrated by preliminary experimental results. Finally, the concept of four network convergence that includes the broadcast based passive radar network is conceived, and its application prospects are discussed.
