Abstract :
In this paper, we propose a modified filtering algorithm to the Lopez and Fabregas [6] noise reduction algorithm for the interferometric phase noise in SAR interferometry using a multiresolution approach. Our contribution to the existing algorithm consists on the exploitation of the InSAR coherence map in order to generate a more adaptive mask for each decomposition level. The developed algorithm is then tested and validated on simulated and real (ERS, SLC) data.
