Abstract :
Airborne L-band fully polarimetric SAR measurements over a boreal forest were analysed as a function of forest biomass. The HV backscattering coefficient was selected for inversion up to 70 m3/ha. HH appears to have information for stem volumes above 70 m3/ha. An inversion scheme was developed from this boreal forest and applied on a temperate forest site.
