Dear Batu,
I generated a pair of SLC (FCOMPLEX or I,Q=4 bytes each; total 8 bytes/pixel), generated master.res and slave.res with gammaReadfiles.csh. Cropping is done with gammaCrop.csh but I changed Data_output_format:complex_real4 in place of complex_short . After coarseorb, coarseorb operation, when I am performing fine coregistration, then most of coh values are coming as nan, e.g.,
INFO : Fine offset between small patches: -361.625, 2.51815e+07 (coh=nan)
INFO : Fine offset between small patches: -361.594, 2.51815e+07 (coh=-nan)
INFO : Fine offset between small patches: -361.562, 2.51815e+07 (coh=-nan)
INFO : Fine offset between small patches: -361.531, 2.51815e+07 (coh=nan)
INFO : Fine offset between small patches: -361.5, 2.51815e+07 (coh=-nan)
INFO : Fine offset between small patches: -361.469, 2.51815e+07 (coh=nan)
INFO : Fine offset between small patches: -361.438, 2.51815e+07 (coh=-nan)
INFO : Fine offset between small patches: -361.406, 2.51815e+07 (coh=nan)
INFO : Fine offset between small patches: -361.375, 2.51815e+07 (coh=-nan)
INFO : Fine offset between small patches: -361.344, 2.51815e+07 (coh=nan)
INFO : Fine offset between small patches: -361.312, 2.51815e+07 (coh=nan)
What could be the issue?
Is it something to do with endian format (as Gamma results are in big endian formats and my machine is little endian)
, or data format (between short and float)?
while running gammaReadfiles.csh I didn't change the endian as you gave example in one of such tutorial (
http://osmanoglu.org/supplement/gamma_readfiles_for_doris/gammaReadFiles.pdf).
Here, I am attaching,
master.res, slave.res and master_slave.res files. Kindly help to solve this issue.
