| 摘 要： | DVB-S 信号作为星基外辐射源信号，在机载、舰载等远离地面辐射源的接收平台中具有较高的应用价值。该文对DVB-S 外辐射源雷达的模糊函数和分辨特性与系统几何结构之间的关系进行了全面系统的分析。文中从DVB-S 信号的特点出发，结合其作为外辐射源信号的无源雷达系统的几何结构，对信号的模糊函数进行了深入的分析，在此基础上，进一步推导了系统的分辨性能与双基地几何位置之间的关系，并提供了其作为外辐射源雷达系统的性能量化结果。理论分析和仿真结果表明DVB-S 信号是一种比较理想的可以作为外辐射源的雷达信号。

| Abstract: | This paper gives the performance research on the ambiguity function and resolution of passive radar based on DVB-S (Digital Video Broadcasting-Satellite) signal. The radar system structure and signal model of DVB-S signal are firstly studied, then the ambiguity function of DVB-S signal is analyzed. At last, it has been obtained how the bistatic radar position impacts the resolution. Theoretical analyses and computer simulation show that DVB-S signal is applicable as an illuminator for passive radar. |
