摘要

Signal band and Doppler band are very large in order to realize precise imaging of high-resolution spaceborne spotlight SAR. At the same time normal imaging methods can not satisfy the radar system coverage performance and the precision of imaging. This paper offers a kind of high precision imaging method for high-resolution (0.3 m) space borne spotlight SAR. This method utilizes Deramp Chirp Scaling and the cubic correction method, and offers a Deramp Chirp Scaling algorithm with cubic correction for space borne spotlight SAR. The method proved effective by the simulation.
