With the great development of synthetic aperture radar (SAR) technique, more accurate and efficient coregistration is needed for high resolution interferometric SAR (InSAR) data before phase filtering and unwrapping. To improve the time efficiency and the coregistration accuracy for meter/dimeter-level resolution data, this paper proposes an adaptive subpixel coregistration method, which brings the adaptive window for the maximum spectrum peak algorithm (MSP A). Experiments are performed on both stripmap data and spotlight data to validate the effectiveness of the proposed method.
