Abstract
En 中文
Forest height is a critical component of ecological and environmental assessments, playing a vital role in modern forest management, biomass estimation, and climate modeling. This manuscript presents a novel single polarization forest height inversion (SPFI) method that uses only single polarization interferometric synthetic aperture radar (InSAR) data without the assistance of auxiliary information. In the SPFI method, the probability density functions (pdfs) of forest height and terrain phases are constructed, followed by the estimation of the differences between adjacent forest heights using the phase gradient, and then the absolute forest heights are obtained by the integration of the relative forest heights. The effectiveness of the SPFI method is validated through experiments conducted at three distinct test sites, using airborne P-band InSAR data and spaceborne L-band InSAR data.
