S-Band Spaceborne SAR Interferometric Coherence Analysis: A Study Case in Peth, Australia

S-band spaceborne synthetic aperture radar (SAR) systems were relatively rare since most launched missions worked in L-, C- or X-bands. An S-band spaceborne SAR should have a better interferometric coherence and penetration capability compared to a C-band spaceborne SAR, which is not fully known. In this paper, we analyze the interferometric coherence based on NovaSAR-1 data in a case in Peth, Australia. Typical regions of interest (ROIs) were selected and the performance was compared to C-band Sentinel-1 data. The results show that S-band spaceborne SARs have better penetration towards shallow and sparse vegetation regions and higher temporal coherence than C-band systems.
