To advance the investigation of vegetated terrain using polarimetric remote sensing techniques, it is important to determine the electromagnetic properties of key constituents, such as branches and trunks, which may be realistically modeled by tapered cylinders. To this end, we apply our previously proposed virtual partition method (VPM). Numerical simulations demonstrate that VPM possesses the desired features, such as high fidelity prediction of the scattering amplitude function and fulfillment of energy conservation as well as the reciprocity theorem. It thus may be helpful in the pursuit of better coherent scattering models of vegetated terrain, a finer understanding of PolInSAR imagery, and a better characterization of scattering mechanisms.
