SAR Complex Images Subpixel Co-registration

Abstract

Generation of correct SAR interferometric images and differential interferometric images, a precise co-registration of SAR complex images is required. In the present study, an algorithm for modeling pseudo SAR images is suggested to illustrate subpixel co-registration. Based on the spectral definition of the spatial SAR images a spectral co-registration algorithm with subpixel precision is developed and numerically experimented.
