Difference between Phase calculated using Band Math option and Multilook operation

Please take a look at this

Fault Deformation Steps

You should use the TOPS coregistration rather than using cross correlation and warp. Otherwise you may get phase jump between bursts in some scenes. Speckle filtering is applied only on the intensity and your output will not be complex data. The Goldstein filter is to make the phase less noisy. The azimuth and range filtering is to filter the non-overlapping spectra when the Doppler centroid frequency of the master and slave products are different.

Hi, What Id like to mention is that the S1A needs cor. accuracy 0.1 in azimuth and 0.8 in range to avoid the jumping phase, especially if the study area is located in two or more than two bursts, that also what I personally phased in my PhD using the ERS-1\2 and ENVISAT, You could find more details about this in 2.6.1.1 image co-registration in the following reference and “Although the processing of the IWS (TOPS) mode requires additional processing steps and the coregistration has to be…
