EVALUATION OF AIR TRAFFIC CONTROL RADAR WEATHER DATA.
Abstract
A Technical Evaluation of the ARSR Weather Surveillance System, Type FAA-ER-240-003, was conducted at the ARSR-1E Facility, Suitland, Maryland, and the Washington ARTCC, Leesburg, Virginia, to determine a system performance level which would permit an effective Operational Evaluation. The ARSR Weather Surveillance System, Type FAA-ER-240-003, purchased from the Raytheon Company, Wayland, Massachusetts, under Contract FA WA-5138, was designed to process weather information received as RF signals at the ARSR-1E antenna and present three distinct iso-amplitude contours of the weather on the Air Traffic Controller's display. An investigation designed to examine the various aspects of the equipment's performance constituted the Technical Evaluation. The ATC Channel circular polarization punch-through level was measured along with the peak intensity of a storm. Contoured weather presentations were photographed and compared with the U. S. Weather Bureau WSR-57 information. It was concluded that a solid line contour, 7 db above the minimum discernible signal and the application of an MSTC-R3 sensitivity variation with range established in acceptable system performance level for presenting weather information. The ARSR Weather Surveilance System is suitable for use in conducting an Operational Evaluation. In addition, improvements can be achieved in several system areas. It was recommended that the Operational Evaluation proceed under established operating conditions. It was further recommended that improvements be accomplished in several system areas.
