| Abstract: | As the guidance parameters of approach landing systems are very sensitive to the environmental effects of airports, it is necessary to perform a numerical system simulations (NSS) for approach landing systems. To solve the multipath effect, the NSS based on Geometrical Theory of Diffraction (GTD) for approach landing systems is presented, including the methods that have been applied, and the simulation results for hangars problem. |
