  • Based on the traditional DBS (Doppler Beam Sharpening) method and the least squares linear fitting algorithm, a new high resolution DBS imaging algorithm is delivered in this paper. The coherent processing number is discussed at first, and the range migration is corrected later. Eventually, as the focus processing of SAR, the azimuth dechirping technique is presented to improve the azimuth resolution. The processing results of real airborne radar data prove the effectiveness of the algorithm.
