Abstract: The development of Synthetic Aperture Radar (SAR) satellite is summarized. A new concept of high-elevation angle, double-side looking SAR satellite system is introduced According to the analysis of the users requirements and the key technical restriction, the performance of radar coverage is analyzed with the optimal orbital elements design for SAR satellite, and the beam position parameters design and system performance analysis are implemented. The space-ground integration approach of mission analysis for SAR satellite is proposed, basing on the characteristics of SAR payload. The computer simulation results are presented, which illustrates the validation of the new approach and the feasibility of high-elevation angle, double-side looking SAR satellite concept.
