摘要

本文提出了一个改进的双射线模型，统一了均匀衍射理论(UTD)，强调了衍射对楔形和大气效应的影响。为了验证所提出的公式，对2 GHz标准大气条件下的完美导电楔问题，将改进的双射线模型与分步抛物方程(SSPE)算法进行了比较。与SSPE数值解相比，改进的双射线模型在路径损失结果上表现出相似的行为。

Scattering by a PEC Wedge in a Standard Atmosphere: a Modified Two-Ray Model Versus a SSPE Algorithm

This work presents a modified two-ray model unified with Uniform Theory of Diffraction (UTD) emphasizing the diffraction effects on a wedge and atmospheric effects. To validate the proposed formulation, a comparison between the modified two-ray model and the Split Step Parabolic Equation (SSPE) algorithm is made for a problem of a perfectly conducting wedge and standard atmosphere conditions at 2 GHz. The modified two-ray model showed similar behavior for pathloss results, compared to the SSPE numerical solution.
