An Examination of Signal-to-Noise Enhancement at the Edzell CDAA (Circular Disposed Antenna Array).
Abstract
A comprehensive survey was made of factors that might yield an increase in signal-to-noise performance of the Edzell circular disposed antenna array including the improved knowledge and control of internal site and system generated noise, external noise from nearby sources, external noise from distant sources, system generated spurious noise and parasitic oscillations, dynamic range limitations of the RF distribution system, and noise entering or leaving the ground system. The impact of each of the above factors on total site performance was examined in order to better understand the benefits that could be realized from various site improvements. Extensive measurements were made of signals and noise at several points in the RF distribution system. Any factor that limited signal-to-noise in the RF distribution system was examined. Originator-supplied keywords are: intermodulation; manmade radio noise; power line noise; electrical grounding; radiofrequency interference. (Author)
