摘要：
This paper presents the first results obtained by repeat-pass bistatic synthetic aperture radar (SAR) interferometry using a fixed C-band ground-based receiver and the Sentinel-1A/B satellites as transmitters of opportunity. The methodology developed to obtain repeat-pass bistatic SAR interferograms uses as input a stack of range compressed bistatic acquisition data and mainly consists in the following stages: raw interferograms computation on a two-dimensional grid in ground geometry, atmospheric phase screen removal and topographic phase compensation. The displacements of a high-rise building were estimated using two stacks of bistatic SAR images acquired between April-June 2017 over an area of Bucharest city, Romania.
