Radio propagation characteristics modeling under typical scenarios
-
摘要: 为了解决某些典型场景(如海上、山区、丘陵、城区)下无法使用已有基础模型来全面表达电波传播特性的问题,建立了一种在典型场景下,基于确定性抛物方程、适用于多个传输场景的统一电波传播模型。把典型场景等效为损耗介质层来求解边界条件,利用Fourier分步步进法得到相应解,然后得到电波在典型场景下的传播损耗,并进行了理论分析和实验验证。结果表明,在不同传输场景下,将统一电波传播模型与Miller-Brown模型、射线追踪模型进行比较,结果较吻合,验证了其正确性。这一结果对建立一种求解典型场景下电波传播衰落问题的统一电波传播模型是有帮助的。

Abstract: In order to solve the problem that the existing basic model could not fully express radio propagation characteristics under some typical scenarios (such as sea, mountains, hills and urban), a unified radio propagation model under many typical scenarios was established based on deterministic parabolic equations. Firstly, different typical scenarios were equivalent to lossy dielectric layers to compute the boundary conditions. Then, the corresponding results were solved by Fourier split step algorithm. Finally, radio propagation loss under typical radio scenarios was calculated. After theoretical analysis and experimental verification, the uniform radio propagation model under different transmission scenarios is compared with Miller-Brown model and ray tracing model, the results are in good agreement. The results are helpful to establish a unified radio propagation model under typical radio scenarios to solve the problem of radio propagation loss. -
