Abstract :
The backscattering coefficients for Black Spruce and Aspen at an incidence angle of 50 degrees obtained using a helicopter mounted C-band scatterometer are related to leaf area index and biomass for several dates while leaves are present. These data are compared with estimates obtained from the Fung disk model for aspen. Implications for spacecraft SAR (eg SIR-C) systems and their ability to determine biophysical characteristics of forest canopies are discussed in light of these results.
