Vegetation canopy height estimation in dynamic tropical landscapes with TanDEM‐X supported by GEDI data

Methods in Ecology and Evolution, Volume 14, Issue 7, Page 1639-1656, July 2023., 2023
Abstract Vegetation canopy height is a relevant proxy for aboveground biomass, carbon stock, and biodiversity. Wall‐to‐wall information of canopy height with high spatial resolution and accuracy is not yet available on large scales. For the globally consistent TanDEM‐X data, simplifications are necessary to estimate canopy height with semi‐empirical ...

Terrain effect analysis and compensation method for polarimetric synthetic aperture radar interferometry height parameter inversion

IET Radar, Sonar &Navigation, Volume 16, Issue 12, Page 1924-1935, December 2022., 2022
Abstract In this paper, the terrain effect on parameter inversion performance of polarimetric synthetic aperture radar (PolSAR) and polarimetric SAR interferometry (PolInSAR) are analysed first. Based on the analysis of the terrain effect on single pixel processing, the terrain effect between adjacent pixels is addressed for both PolSAR and PolInSAR ...
