Difference between vertical and LOS displacement

Hello everyone, I am trying to estimate building subsidence for the area of Ho Chi Minh in Vietnam. I have used 6 interferograms (between June 2016 and June 2017) where I stacked them and produced the subsidence map. Firstly, I produced displacement in LOS geometry using the following equation. unwrapped (phase * wavelength) / (-4 * PI) (or ‘phase to displacement’ from SNAP where the results are the same). I also calculated the vertical displacement using the following equation: (unwrapped ph…

Phase to Displacement Units?

After the unwrapping successfully executes, I want to apply Phase To Displacement, then Range-Doppler Terrain Correction. I understand that the unwrapped values are in radians. When Phase To Displacement is applied, what are the units the result is in? From there, I want to apply the Range-Doppler Terrain Correction so I can bring the result into ArcMap in the right place. When I look at this final result in ArcMap, it makes sense that the units would be in meters, but nothing tells me for sure…
