摘 要： Radio navigation aids like the Doppler Very High Frequency Omnidirectional Radio Ranges (DVOR) are sensitive to scattering objects like buildings and wind turbines. Due to multipath and shadowing effects the propagation of the corresponding "signal in space" is disturbed and deviations of the transmitted navigation content are expected. Existing analytical and numerical methods to determine the induced bearing error in space are often aimed at estimating just one value for the expected maximum error in a specified space volume or at most provide 2-dimensional observation surfaces, on which the error is represented by color mapping. However, in order to understand the propagation of bearing error in space, a 3-dimensional investigation is essential but often not realizable due to very high computational effort. In this paper a method is presented to calculate the 3-dimensional texture of the bearing error while constraining computational effort to a reasonable amount.

多普勒甚高频全向无线电测距仪（DVOR）等无线电导航设备对建筑物和风力涡轮机等散射物体非常敏感。由于多径效应和阴影效应，相应“空间信号”的传播受到干扰，导致所传输的导航信息出现偏差。目前用于计算空间中诱导航向误差的分析与数值方法，通常仅旨在估算指定空间体积内最大预期误差的一个数值，或最多提供二维观测面，并通过颜色映射来表示误差。然而，为了理解空间中航向误差的传播特性，三维分析是必不可少的，但由于计算量过大，这种分析往往难以实现。本文提出一种方法，在合理控制计算资源的前提下，计算出航向误差的三维纹理。
