Error in coherence estimation for COSMO SkyMed

#1

Hello everyone

I am working on 10 different COSMO SkyMed images and when I tried to estimate the coherence, I got the following Error message.

I did the following preprocessing on images:

  1. Radiometric correction: Radar → Radiometric → Calibrate
  2. Coregistration with a master image: Radar → Coregistration → Coregistration
  3. Select the Band to extract each coregistered image: Raster → Data Conversion → Select Band
  4. Create a stack for each of two adjacent images: Radar → Coregistration → Stack Tools → Create Stack
  5. Coherence estimation: Radar → Inferometric → Product → Coherence Estimation

How can I fix the problem? If there is any mistake in preprocessing, please let me know.

Thanks in advance

@djagula can you have a look?
Thanks

A JIRA ticket ([SNAP-3629] - JIRA) has been created to track the issue. We will look into it, thank you.

If your goal is to estimate the coherence of two complex products, you can follow the steps below:

  1. Radar → Radiometric → Calibrate
  2. Radar → Coregistration → Coregistration
  3. Radar → Interferometric → Products → Coherence Estimation
    No band selection or create stack is needed.
