             abstract = "This paper explores an automatic registration procedure for use on 
                         single-look complex InSAR image pairs. The procedure is divided on 
                         two distinct parts. First a coarse registration is done using the 
                         phase correlation technique. The coarse registration is a global 
                         registration method that calculates the vertical and horizontal 
                         shifts on a pixel scale. The calculated translation is applied on 
                         the second image without need of interpolation. The new pair is 
                         then processed with the fine registration. At this point a grid of 
                         small window pairs is equally distributed through the images. Each 
                         pair is zero-padded to avoid circular convolution issues and is 
                         transformed using Fourier transform. Subpixel resolution is 
                         achieved zero-padding the frequency by a given factor before 
                         applying the same phase correlation technique, now as a local 
                         registration method. Control points are defined as the center of 
                         each pair of windows processed and are saved on a list with 
                         calculated subpixel shifts. At the end a polynomial transformation 
                         is calculated based on least squares using the list of control 
                         points and subpixel shifts. Finally the second image is 
                         interpolated. This procedure was implemented on IDL/ENVI and 
                         tested on two data sets, X-Band R99 and L-Band SIR-C. Results show 
                         that it is possible to automatically produce better interferograms 
                         as the number of residues is reduced.",
