strange remained orbit ramp in bistatic TDX-TSX interferometry

[Mohammad Mohseni Aref]

Dear Batu,

I have tried to extract DEM using bistatic TDX-TSX usingadore .Actually,.As you see in my result in png format a kind of curvature remained in wrapped interferogram .I have done deramping as well and I couldn't get final good result.I think this problem is related wrong baseline estimation or wrong phase simulation from orbit data.What's your suggestion?

Hi Mohammad, 

You can remove a second order ramp in range dimension using deramp from the unwrapped solution.

Hi Batu,

The point is it is not second order ramp in range!I have done already deramping using adore deramp function( -o 2 and other option!) and also I have examined 1 to 10 order deramping using my own code.

Best,

Mohammad
