Issue with Back-Geocoding after Thermal Noise Removal on Sentinel-1 SLC Data

Microwave Toolbox
1

Hi all,

I am trying to estimate the interferometric coherece for Sentinel-1. So far, I have applied the TOPS Split and Apply Orbit File. After that, I performed the Thermal Noise Removal, following the methodology described in Mascolo et al. (2022) (I did not apply the TOPS-Deburst as I intended to apply the Back-geocoding afterwards):

Mescolo et al. (2022) described methodology for Thermal Noise Removal, but for the TOPS-Deburst

The issue arises after this preprocessing step: the outputs generated after the BandMerge seems to be incompatible with Back-Geocoding. Specifically, I’m encountering the following issue:

Despite the metadata stating that the product is SLC, the product type is recognized as BandMath:

When I try to set the parameters for Back-Geocoding, I get the follwoing error:

Has anyone encountered this problem? Any suggestions on how to resolve this issue or make the BandMerge output compatible with Back-Geocoding?

Thank you!
