This paper presents a robust misregistration estimator based on ESD method for TOPSAR interferometry. For the in-terferometric applications of TOPSAR mode data, a master and slave SLC pair requires a coregistration accuracy in the milli-pixel order due to the large Doppler centroid frequency variation. Although ESD method estimates the misregistration with the required sensitivity, a prior fine coregistration step is a prerequisite. This paper presents an advanced coregistration method that relaxes the fine coregistration requirement of the ESD and improves the estimation sensitivity. Experimental results with Sentinel-1A data are shown to validate the proposed method.
