Hello @ABraun ,
Could you help me about the formula of conversion phase to elevation? I could not find this formula and I need that to conversion of elevation to phase. Please help. Thanks.

I don’t know the exact formula, sorry.

You can download there the .pdf. This is a very good article for beginners, with all the maths written without too many shortcuts. Your formula is given in equation (13)

Thanks @qglaude,
Also, do you know any idea to change my DEM (meter) map to phase map? I looked this formula to get idea but it is related to SAR to DEM conversion. I could not transform my DEM map to phase map via this formula. Any idea helps much. Thanks.

If you know you height ambiguity, the relation is straightforward.

Let’s say your height ambiguity is 274.56 meters, you just convert your DEM to radians by multiplying your DEM (meter) by

 2 * PI / 274.56

Note that your height ambiguity can be found in the stack overview module.
