You can do this with the ESA SNAP toolbox.

After you import the .N1 file, the global incidence angle is stored under Tie-Point-Grids > incident_angle (you can convert it to a regular raster in the band maths)

The local incidence angle is created during Range Doppler Terrain Correction and can be created as a separate output band.

Andreas Braun Ibtisam Marie thank you for your answers. I used interpolation between the range sample number and incidence angle at those tie points, from geolocation grids to get pixel wise incidence angle.
