What is the acquisition mode of your Capella data? Stripmap or spotlight mode?

Hi,

The acquisition mode is spotlight.

Hi,
I noticed the same issue (clipping) during Range Doppler Terrain Correction. I was working with SAOCOM, Envisat ASAR, Iceye (Spotlight) SLCs, both acending and descending

Hi,
I wanted to check if there are any alternative software tools available for performing terrain correction on Capella SAR data.

Thank you for your time and assistance.

Best regards,

Spotlight would at least require deramping for things to work properly with stripmap co-registration. @jun_lu
