Issue in goldstein phase filtering

Hello, I’m trying to play the goldstein phase filter, and I find I haven’t been able to use that operator(ಥ﹏ಥ),can somebody tell me why it happened or how to solve it?

I really followed the normal processಠ╭╮ಠ.

what data are you using and which steps did you apply so far? What is the poduct you use as input for the goldstein phase filter?

I’m using S1B, before goldstein phase filter I operated subset–>multilooking–>calibrate–>terrain correction, and I use interferometric–>filtering—>goldstein phase filter.

The goldstein phase filtering can only be applied on interferograms. If you want to smooth your image, you have to apply one of the speckle filters.

Besides that, if you are working with GRD products you can skip the multi-looking, because you already have square pixels. .
