Evaluation of the Deformation Measurement Efficacy of GNSS-Based InBSAR in Vegetated Areas: Preliminary Assessments

Global Navigation Satellite System based bistatic Synthetic Aperture Radar Interferometry (GNSS-based InBSAR) is an effective approach for achieving high-precision 3D surface deformation measurement. However, existing studies on the vegetation effects on deformation measurement using GNSS-based InBSAR have rarely been conducted. In this paper, a preliminary assessment of deformation results in various vegetated areas using GNSS based InBSAR with Beidou Navigation Satellite System (BDS) data is implemented. The imaging results and deformation measurement accuracy are analyzed. Current results prove the feasibility of GNSS-based InBSAR in analyzing vegetation decoherence.
