Image extra-coregistration based on GIP for radar applications

• Image coregistration is a mandatory procedure for radar applications such as synthetic aperture radar change detection. The spatial coregistration can be easily handled with geo-reference, whereas radiometric coregistration requires much more effort due to the randomness of noise and clutter. The performance of a coregistration method is usually measured by the correlation coefficient that is desire to be close to unity. However, the currently used methods cannot provide coregistration with such correlation coefficient value. The paper introduces an image extra-coregistration method that helps to increase the correlation coefficient between the radar images close to unity. This strongly supports radar applications such as change detection. © 2022 IEEE.
