Abstract

GEO SAR (Geosynchronous Synthetic Aperture Radar) has great potential for SAR tomography applications because it can obtain large amounts of data from the same scene due to the advantage of one-day revisit time. In this paper, we analyze the performance index of GEO SAR tomography in squint mode, and design the orbital elements of satellites at different inclination angles according to the performance requirements. The results show that the squint mode does not affect the perpendicular baseline of GEO SAR, but it can lead to the decrease of ambiguous height. GEO SAR tomography can be realized by adjusting the semi-major axis. The higher the inclination, the greater the adjustment amount of the semi-major axis.
