Error during advanced Spectral Diversity

2020-08-31 15_02_02-S-1 Enhanced Spectral Diversity

This error occurs when processing advanced spectral diversity, what is the reason for this error?
I get this error when I try to apply advanced spectral diversity to two pairs of SLS images. And no matter how much I changed the images, the same error occurred again. What is the solution to this problem?

what exactly is the input data in this operator?

The data used in this work are two consecutive images of Sentinel-1 in IW and SLC format. And after I selected the image based on IW, I started processing Orbit File and Back Geokoding.

The first step should be TOPS Split where you select one sub-swath and the amount of bursts.

I did this step too. I just selected a sub-swath and then the amount of bursts was disabled.2

Was the coregistration successful? Please check if the second bands contain data.

If you want to do interferometry I also recommend selecting VV during TOPS Split (and reducing the bursts as much as possible).

Thank you for your help.
