The BISAR system based on navigation satellite signals attracted more and more attention for its advantages. The concept of average ambiguity function was introduced in this paper in order to analyze the resolution capability of BISAR system independently of the particular pseudo-random code, and the generalized ambiguity function (GAF) of the system was studied. Then average GAFs of BISAR system based on different GNSS signals were calculated to compare their resolution performance. The results indicated that the trajectory of navigation satellite had a great influence on the performance of the BISAR system and BDS signal had the best resolution capability.

Key words: BISAR, transmitter, navigation satellite, pseudo-random code, ambiguity function, resolution capability
