Forest biomass retrieval using P-band synthetic aperture radar (SAR) data has been studied during the past two decades. However, much progress remains necessary to recover biomass for tropical dense forests, where above-ground biomass (AGB) values are often found between 250 and 400 t/ha. In this high range, the sensitivity of radar backscatter to AGB is small and can be obscured by disturbing effects. These are related to measurement errors, forest characteristics, and environment variations… CONTINUE READING
