SAR Image Registration Based on Monogenic Signal Theory

A new algorithm is proposed for SAR image registration based on monogenic signal theory. A monogenic phase congruency function is constructed using the characteristics to detect feature points in SAR image. On the other hand, a monogenic vector is composed by the 3-triple components to solve the problem of feature points matching in reference SAR image and sensed SAR image. Diverse SAR image data are used for verification and the experiment results indicate that the proposed algorithm has a good performance of SAR image registration.
