Topographic Correction for Biomass Retrieval from P-band SAR Data in Boreal Forests
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2010
The influence of the ground slope on radar backscatter
has been proven to be greater for lower radar frequencies due
to deeper canopy penetration. In this study, multiple heading, Pband
SAR data of boreal forest in Sweden was used to find a
model for topographic correction for improved biomass retrieval.
Eleven models were tested and the best model was selected. The
selected model was then used for biomass retrieval. Even by
means of the most simplified approach, forest biomass could be
established with a root-mean-square error of approximately 50
t/ha for HV and 66 t/ha for HH.
