Abstract

Phase unwrapping requires - implicitly or explicitly - phase gradient estimates for phase reconstruction. An asymptotically unbiased local frequency estimator based on multiresolution signal representation is presented. The proposed estimator is able to automatically trade-off resolution against estimation error. It is shown that interferometric SAR processing can be improved by employing a smoothed version of the unwrapped phase. Particularly, a novel method for slope-adaptive spectral shift filtering is introduced.
