近年来，可靠的双站散射模型的发展，用于检索高质量的地质数据，如土壤水分的信号的机会（SoOp）反射计一直是一个非常感兴趣的主题。本文扩展了我们以前的双基地模型，包括右手圆极化（RCHP）入射波的情况。我们提供了一个完全双基地雷达散射模型从SoOp（线性和圆偏振入射波）在L波段和P波段的植被地形。该模型考虑的三种主要散射机制包括地面直接散射（G）、植被体积散射（B）和植被地面双反射散射（TG和BG）。此外，稳定化扩展边界条件法（SEESTAL）被用来代替小扰动法（SPM）的粗糙表面散射分析。
In recent years, development of reliable bistatic scattering models for retrieving high quality geological data such as soil moisture from Signals of Opportunity (SoOp) reflectometry has been a subject of great interest. This paper extends our previous bistatic model by including Right-hand Circularly Polarized (RCHP) incident wave scenarios. We provide a fully bistatic radar scattering model from SoOp (linearly and circularly polarized incident waves) at L-band and P-band for vegetated terrains. The three major scattering mechanisms considered in this model include direct ground scattering (G), vegetation volume scattering (B), and vegetation ground double-bounce scattering (TG and BG). Moreover, the Stabilized Extended Boundary Condition Method (SEBCM) is used in lieu of Small Perturbation Method (SPM) for the rough surface scattering analysis.
