geocode calibration parameters and noise LUTs #130

Closed seongsujeong closed 1 year ago

seongsujeong commented 1 year ago

This is a follow-up of #114 #119, which were the placeholders for the geocoded radiometric calibration parameters, and thermal noise LUTs respectively. This loads the calibration parameter LUTs from Sentinel1BurstSLC, geocode them, and write that into the output.

@seongsujeong please, let's work and close off this PR. Thanks

Just did a comparison between multilooked radargrid, and the custom-calculated radargrid. The point here is that the decimated LUT covers the CSLC as much as possible, so that we avoid weird interpolation result on the edges. The screenshots below are the comparison

Below are from the same data, but on the lower edge

The overall shape of the geocoded LUT is as in the screenshot below. The bluish burst in the back is the amplitude of CSLC, and the magma colomapped block is the geocoded LUT.

@LiangJYu @vbrancat I think this PR is ready for another round of review. Would you mind taking a look? Thanks.
