BandMaths problem

Hi !

I was trying to do a really easy thing and I didn’t manage to do it …

My goal was to do a ratio between two amplitude band from 2 GRD S1 images and the amplitude average of both.

But i don’t find how to do it ! I can’t from the bandmath select on the toolbar, i tried with a graph but none of them allow me to select both band. I can only select one band from one or the other image.

Can you help me ? Is there a method I didn’t see ?

Thanks in advance.


you first need to bring them into one new dataset. You can achieve this with
Radar > Coregistration > Stack Tools > Stack

or if you have data from different tracks:
Radar > Coregistration > Coregistration

The new dataset will have both amplitudes and you can select them in band maths.

Okay thanks.

In fact now you tell me it’s pretty obvious…

That would work on flat areas but in the general differing-tracks-case one should do Terrain Correction to the same projection and then stacking.

you’re right, that would be more correct.
