A THEORETICAL EVALUATION OF THE FPS-6 RADAR ANTENNA IN TROPOSCATTER COMMUNICATIONS SYSTEMS

Abstract

The report theoretically analyzes the effect of using a fan-shaped antenna reflector, having an aspect ratio of 3.5 to 1, for troposcatter communications. The analysis is performed relative to the performance which would be achieved when using a circular cross-sectioned parabolic reflector having the same free-space antenna gain. Parameters which are considered in the analysis include the orientation of the fan-shaped reflector, aperture-to-medium coupling loss, differential path delay, and scatter models based on Waterman and Friis-Crawford-Hogg.
