A SAR image registration algorithm based on target detection

This paper presents an algorithm about SAR image registration based on target detection. This method detects the strong scatterers target firstly, secondly calculates the centroids of the targets, then these centroid points are used to generating Delaunay triangulation, after triangulation, the centroids - incenters, circumcenters of the corresponding similar triangles are used to establishing the maping function between master-image and slave-image. Finally, the test carried out with SAR images of ERS-I satellite , comparing with the methods based on cross-correlation, the experimental result confirms the effectiveness of the proposed approach.
