This paper gives the performance research on the ambiguity function and Flight Boards 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 Safety Shoes 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.
