Fig. 4From: Bistatic scattering simulations of circular and linear polarizations over land surface for signals of opportunity reflectometryScattering mechanisms in the first-order Bi-mimics model, including the GCG, CG, DC, GC, GT, DG, and TG terms. The SG term is not shown. The crown layer depth is Z1=d and the trunk layer depth Z2=HtBack to article page
