MODELS OF MULTIPATH PROPAGATION EFFECTS IN A GROUND-TO-AIR SURVEILLANCE SYSTEM

Models are developed for the electromagnetic propagation of diffuse and specular multipath for a surface-to-air ATC radar beacon link. The models take into account geometrical, topographical, electrical, and surface characteristics of the multipath propagation environment. The models are used to evaluate signal fading and azimuth estimation performance of a monopulse processor in a ground-based interrogator. The results are applied to assessing the performance of the DABS sensor. Conclusions and recommendations for experimental work are presented. (Author)
