✦ Synopsis
Variations and fluctuations of forest floor scattering was soil rms height, whereas, at C-band, all parameters were about equal in influence. The modeled sensitivities properties can lead to variability in radar backscatter from forest, thereby interfering with SAR backscatter-suggested that the surface-related uncertainty in forest backscatter at L-HH and L-VV, and at C-HH and C-VV based estimation of forest biophysical characteristics. Understanding how forest backscatter varies over the range at steep incidence angles, may be unacceptably large for many applications. ©Elsevier Science Inc., 1998 of probable surface conditions is important in the selection of appropriate radar bands and incidence angles for forest sensing applications and for quantifying uncertainty of the derived forest characteristics.
