Abstract
This paper focuses on the performance degradation of glide slope (GS). GS guides pilots regarding their vertical position with respect to an approach path that is formed using ground-reflections. Irregular ground features are known to scatter electromagnetic waves and produce positional errors. Numerical simulations can provide possible solutions for predicting unexpected influences of these scattered electromagnetic waves. We discuss numerical techniques based on the ray-tracing method for two and three dimensional ground models. Propagation paths are estimated from the shortest path along a straight line between a source and a receiver. We discuss how the proposed numerical method works for different ground shapes.
