S1 radiometric correction

[ABraun]

the incidence angle is present in the tie-point grids and can be used as such in the band maths.

Local incidence angle (SAR grid)

I don’t have a solution but maybe a hint: You can, in a first step, download the DEM in slant range geometry by right clicking on the band > Add Elevation band. You would then be able to derive it based on elevation and the incidence_angle tie-point grid somehow in the band maths operator but I don’t know the formula either. [image]
