Abstract:

Base on the earth, moon and satellite trajectories, the geometric model of ground-satellite SAR is presented. The ambiguity function of ground- satellites bistatic SAR is defined and the ambiguity function formula is derived. Moreover, we analyzed the ambiguity function of ground-satellite SAR through numerical simulation. The simulation results demonstrate the validity of proposed function. Furthermore, it is the theoretical basis for the subsequent research on the imaging algorithm.

Key words: ground-satellite, bistatic SAR, ambiguity function, synthetic aperture radar(SAR)
