This paper focuses on the multipath interference by an obstruction or rough terrain is studied. The detriment of Glide path information to an aircraft that is approaching the airport with a precision ILS (Instrument Landing System) landing is due to the wrong siting. Terrain irregularity or roughness is the worst and most common glide slope siting deficiency. The degrading effect of rough terrain results from the random dispersion and/or phase shift of ground plane signal. In order to study the possibility of glide path signal interference, the new site that is under construction a big apartment complex and 3km distance away from glide path antenna is selected as a representative model in domestic airport. In the study, computerized simulation technic is employed to predict the probable reflected energy caused by the multipath conditions from antenna, obstructions and siting criteria. This study suggests the solution of a similar case through this analysis method.
