I am trying coherence calculation for TerraSAR-X Staring SotLight data.
According to this DLR paper, for spotlight data I need to bring the Doppler spectra to match before I can calcuate the interferogram/corherence.
We have run your graph with the Uluru_SlidingSpotlight TerraSAR-X data we have and the default settings of the operators. Unfortunately we could not reproduce the stripes in the result (see images below). What parameters did you use in your processing?
Thanks for looking at my issue, jun_lu, but the stripes do not occur in TerraSAR-X High Resolution SpotLight images over Uluruh, Australia, that you’re showing here. My example came from a Staring Spotlight (squinting forward and backward by 2.1 degrees each), an image pair over Rotterdam.
