摘要

The potential of Split-Band processing to determine the absolute phase of an interferometric pair of SAR images has been demonstrated in previous studies. In this work we propose a new approach based on the joint use of Split-Band Interferometry and SAR Interferometry for the phase leveling of disconnected regions of an unwrapped interferogram. In this paper a new selector of frequency-persistent scatterers is presented. In order to demonstrate the applicability of the method we propose an artificial disconnection of the regions to validate our results without any ground based measurements. The presented method is tested on TerraSAR-X images acquired with a range bandwidth of 150 MHz over the Nyamuragira volcano in the African region of the Kivu Rift. Several combinations of split parameters are applied and investigated to determine the best configuration for this application.
