Paper Abstract

The phase noise filtering of interferogram is one of important procedures in INSAR data processing. Any improper altering of the wrapped phase may influence the quality of derived DEM, because the interferometric phase contains the topographic information. A new adaptive method combined with Media filter and gradient-based adaptive filter is presented in this paper. The filtering action is conducted in the real and imaginary component of the interferogram respectively before the phase image is formed by means of the arc tangent operator.
