Is there an easy way to get the azimuth of the incident radar pulse for a given pixel in SNAP?


I was wondering if there is an easy way to get the azimuth angle (i.e. the orientation associated with the incidence angle) for a pixel in a SAR image in SNAP? I can get the incidence angle by placing a pin and adding the incidence angle to the pin manager table, but I can’t see a way to do something similar for the azimuth direction.

Many thanks!

The azimuth-angle changes throughout the synthetic aperture during the acquisition. I’m not sure if having this information available would be that useful in the end .

Thanks for your reply. I’m trying to estimate the depth of a pit from the length of the radar shadow in Sentinel 1 SLC images using the incidence angle. However the azimuth angle may have to be taken into account due to differing heights along the pit rim, within the pit, etc… Would I be better of taking it as perpendicular to the travel direction of the satellite? Or perhaps there’s something fundamental I’m missing about SAR and this won’t work …
