Influence of Wave Diffraction on the Coastal Airfield Surface on the Glide Path Behavior

The influence of the diffraction of electromagnetic waves at a limited area in front of the glide path beacon on the behavior of the aircraft approach trajectory for landing is considered. The underlying surface at the coastal airfield is represented by a perfectly conducting half-plane. An asymptotic expansion of a rigorous solution to the problem of diffraction of a spherical wave by an ideally conducting half-plane is used. The calculated results are compared with the experimental results obtained in flight.
