Abstract

In this paper, a modified correlation coefficient algorithm is proposed to accomplish image-registration for repeat-pass SAR interferometry. This algorithm utilizes a new definition of correlation coefficient to improve the calculation accuracy of offset between two images. Our simulation shows that Doppler centroid has a significant influence on the correlation coefficient and it should be removed before registration. SIR-C/X X- band experimental data has been processed to demonstrate the effect of the proposed algorithm. Also quantitative comparison between this paper´s results and the results from the maximum-spectrum method is presented to show the improvement.
