Hi Reda,

I follows Young's slits experiment for calculation of different phase at particular point.

Interferometric SAR and Displacement INSAR are based on young,s slits experiments.

To observations are made from different locations in space at different times, so interferometric phase is proportional to the topography and topographic change. Sensitivity of phase with respect to change is much greater than the topographic relief. Therefore phase is equal to a constant multiplied by the sum of the topography and delta topography.
