Abstract :
Two-way foliage attenuation measurements from UHF and VHF SAR images collected from several USA forests and an empirical model of two-way attenuation versus center frequency are presented. Comparisons of UHF and VHF clutter backscatter coefficient distributions are made for different forest areas and terrain slopes. UHF two-way attenuation and backscatter coefficient statistics are presented for different polarization channels
