Abstract :
Accurate determination of radiated field without resorting to field measurements has been a desired goal in many radio and navigation systems. This paper presents an efficient and accurate computer model which could evaluate the received field at any location. This is done in three steps: modeling of the terrain between the transmitting and receiving antennas, ray tracing and filed evaluation. The model has been applied to an instrument landing system (ILS) glideslope and the results are presented. The results computed from the method developed here are compared with the earlier methods and the actual measurements and good agreement is shown.
