Research on Bi-static SAR azimuth resolution characteristics

In this paper, the problem of Bi-SAR azimuth resolution is studied. Firstly, the three-dimensional bistatic geometrical modal and an approach to azimuth resolution based on gradient are introduced. Then, the main factors influencing Bi-SAR azimuth resolution in practices are analyzed. The computer simulation of the airborne experiment in “Tandem” mode tested the validity of the study at the end of the paper. This study is helpful to the Bi-SAR performance analysis and system design.
