Orbital Phase Correction

[Herman Simanjuntak]

Hello Batu

I've been trying to make DEM with ALOS PALSAR Lv.1.0 but the result unwrapping show error in orbital phase (i've been attached the result). So when i tried convert phase value to height value, there is a significantly value ( eg.19000 m). How should i do to correct the orbital phase?.

Hello Herman, 

I think the best way to go is to use the "deramp" command in ADORE in conjunction with a preliminary DEM. If you have a coarse DEM, you can use that to generate a radarcoded DEM using the "comprefdem" step. Then you can use the *.crddemlp file as an estimate solution and pass it to deramp. 

Let me know if it does not work for some reason. 

best, 

batu
