Abstract :
Image matching is one of the key steps in Processing of InSAR. In order to improve the reliability and the rate of matching, a fast least squares matching algorithm with one-dimensional azimuth searching was proposed. The interferometric SAR images obtained by space-borne ERS-1/2 and by airborne dual-antenna system were employed to do experiments of matching. The results show that the proposed one-dimensional least squares matching algorithm was fast and effective.
