Synthetic aperture radar interferometry using ground slope vector to phase unwrapping

This paper deals with 2-dimentional synthetic aperture radar interferometry. Because of high sensitivity to noise, we propose a two-step phase unwrapping approach. The purpose of preprocessing is to organize the phase by an adaptive filter to improve the estimation of the ground slope vector. The main process smoothes the phase, using the ground slope components, and unwraps the signal. We present numerical and experimental results for synthetic data.
