Abstract :
Optical depth and backscatter measures were made at 18 frequencies between 50 and 450 MHz on two forest stands having dry biomass densities of 323 and 87 tons/ha to identify radar frequencies capable of penetrating heavy stands of vegetation. Good separation between stands was only achieved below 120 MHz
