Impact of seasonal change on deformation measurement performance of GNSS-based InBSAR in vegetated area: preliminary results
Global Navigation Satellite System-based bistatic Synthetic Aperture Radar Interferometry (GNSS-based InBSAR) stands as an efficient approach to realize mm-level deformation measurements. To elucidate the impact of seasonal variations on the performance of GNSS-based InBSAR deformation measurements in vegetated areas, a statistical and analytical assessment of long-term observation data from Beidou Navigation Satellite (BDS) is conducted in this paper. The results demonstrate that there is an obvious improvement in deformation measurements accuracy during 2024.01.01-2024.03.02. This finding is consistent with the arrival of winter and the decreasing trend of surface vegetation density. The impact of seasonal change on deformation measurement performance of GNSS-based InBSAR in vegetated area is validated.
