摘要

The forthcoming launch of the NASA-ISRO Synthetic Aperture Radar (NISAR) mission will open the path to a new type of L-band measurements constituted by dense time-series of polarimetric backscatter and interferometric coherence with unprecedented spatial and temporal sampling. Here, we start the development of a theoretical framework that links L-band backscatter time-series with interferometric coherence measurements. The water-cloud-model (WCM) and an extended version of the random-motion-over-ground (RMoG) model are adopted to express radar measurements in terms of forest above-ground biomass and tree height. Time-series data collected during the 2019 UAVSAR AM-PM campaign in Southeastern United States are used to evaluate the correlation of various PolSAR- and InSAR-derived parameters with field-measured above-ground biomass.
