Abstract :
This work presents a phase unwrapping (PU) algorithm for SAR interferometry based on a particle filter (PF). This PU algorithm performs simultaneously noise filtering and phase unwrapping. The formulation of this technique provides independence from noise statistics and is not constrained by the non linearity of the problem. Results show a significant improvement with respect to conventional PU algorithms in some situations.
