IMPLEMENTATION OF TOPS MODE ON RADARSAT-2 IN SUPPORT OF THE SENTINEL-1 MISSION

摘要

TOPS is the main imaging mode on Sentinel-1 and has been implemented recently as an experimental mode on RADARSAT-2. This paper describes aspects of the beam mode design for RADARSAT-2, and presents the results of expected coherence based on statistical analysis of existing RADARAT-2 InSAR stacks. Performance results for radiometry and point target analysis are presented for the test scenes that have been acquired. Doppler grid results and initial interferometry results are also presented.
