Abstract :
The INSAR imaging is one of the principal working patterns of the distributed satellite SAR system. This paper research mainly the influence of the Earth-movement and the distributed satellite circling to the INSAR imaging precision, analyze and derive the corrected imaging formula and the error curvature, and analyze in detail the height error shift in the variant latitudes and rotating angles. The results of simulation verify that when the latitude is lower and the rotating value is larger, the height error is higher. And the height error is the highest near the equator.
