The invention provides a determination and
analysis method for a three-layer S-RVoG (sloped random volume over ground) scattering model of an inclined forest area. The invention comprises the following steps that: S1, showing a
schematic RVoG model scattering diagram, and focusing on the deducing and the analyzing of a coherence coefficient expression of an RVoG model; S2, increasing the scattering component of a
trunk layer, and deducing a coherence expression of a three-layer scattering model in detail, based on the RVoG model; S3, considering the influence of local
terrain slopes, modifyinga vertical
structure function, deducing an S-RVoG model, and analyzing the model; and S4, considering the scattering component of the
trunk layer, deducing a three-layer S-RVoG model, and analyzing the influence of each physical parameter on coherence, based on the S-RVoG model. The determination and
analysis method solves the problem that the RVoG model is fuzzy in the description of the naturalmountain area
scattering process, improves the
vegetation coherence scattering model, and improves the accuracy of the
polarimetric SAR interferometry vegetation in height inversion.
