Abstract

A theoretical microwave backscatter model was used to simulate the sensitivity of ERS-1 SAR data over temperate forest to SAR system, forest stand, and environmental parameters. Of particular interest were the simulations of the temperature dependence of the backscattering coefficient under consideration of the partial freezing of the soil and plant water at temperatures below 0°C and of leaf and needle biomass variations as they occur due to the seasonal development and as a consequence of stress and disease
