multiple topics have already discussed the vertical or 3D displacement from ascending and descending data combination linked to this formula:
vert_disp = (unwrapped phase * wavelenght*cos(rad(incidence angle)))/ (-4pi )
or this formula:
(unwrapped phase * wavelength) / (-4 * PI * rad(cos(incidence angle)))
including these references: https://www.researchgate.net/publication/225604929_Inferring_three-dimensional_surface_displacement_field_by_combining_SAR_interferometric_phase_and_amplitude_information_of_ascending_and_descending_orbits
but from all this information i am trying to make a matlab script that will take the time_series as presented in ps_plot(‘v-do’, ‘ts’) of both the ascending and descending image stack to merge these into vertical displacement based on raster operations.
for this i would like to know which files contain the incidence angle per pixel and also the deformation per pixel over all image pairs. the documentation on this is almost not available so i hope any og you can give me a head start on which matlab files to use for this script.
