Abstract :
Retrieval of stem volume of boreal forest from SAR images by using electromagnetic scattering model and neural network is presented. The experimental data of Danish Airborne SAR (EMISAR) for the NOPEX southern research area in Sweden were used to test the retrieval scheme. It has been shown that a neural network trained by calibrated electromagnetic scattering model with experimental data has the potential to retrieve the biomass for boreal forests
