About exporting S-1 GRD products' elevation angles

I want to know how to export sentinel-1 GRD products’ elevation angle of each pixels in SNAP software?

Thanks you for your reply in advance.

In case you didn’t find it, it is in the Tie-Point-Grids folder

To Export it, just create a band maths expression elevation_angle to create a new band (not a virtual band so remove the checkbox) and save your product (File > Save Product).

As a last step, export your band as a Band Subset with File > Export > Geotiff
