Combine Ascending and Descending Images

[mwabz.a]

Dear all,
I am new to SAR processing and require some assistance.
I am trying to combine two interferograms one from ascending and descending images to obtain 3D displacements . Can anyone help me with a tutorial link on such?

Have a look at this post please,

Combining ascending and descending data?

Hi all, is it possible to combine ascending and descending Sentinel-1A GRD IW VV data in a simple way, in order to increase the amount/availability of images over my area of interest? What I am thinking of is to follow such an approach (for each of the Sentinel-1A GRD IW VV ascending and descending data acquired): Radiometric - Calibration; Speckle filtering Radiometric - Terrain Flattening Geometric - Range-Doppler Terrain Correction. After this I should have gamma0 for both the descending…

I also think there are already enough topics on this. If you still have questions, try to follow up on a specific point there:

• Phase to Displacement Units?
• Difference between vertical and LOS displacement
• Vertical displacement senitnel 1 interpretation
• Vertical and horizontal displacement
• The phase shift originates from horizontal or vertical displacements

Two posts naming the formulas:

• Phase to Displacement Units?
