BIOMASS RETRIEVAL USING MULTIBASELINE POLINSAR DATA OF A BOREAL FOREST AT L-BAND

摘要

Forest height plays an important role in characterizing forest stand parameters, which can bernrelated to above ground biomass (AGB) through allometric relations. In this work, the forestrnheight and biomass parameters estimation performance using PolInSAR technique isrnevaluated on real airborne L-band SAR data acquired by E-SAR sensor in multibaselinernconfiguration over Krycklan test site. The inversion method will be enhanced by consideringrnthe impact of decorrelation sources such as slope variation. The main purposes of our workrnare to propose improved multibaseline PolInSAR height inversion approach and establishrnrevised model when evaluating AGB over boreal forest by using PolInSAR height results.rnFinally, the validity of the proposed methods will be analyzed.
