Beacon Collision Avoidance System (BCAS) Airborne Antenna Diversity Study.

Abstract

The potential need for antenna diversity on the intruding aircraft was examined. The BCAS system was used for determining airborne antenna diversity requirements for general aviation aircraft approaching a BCAS equipped aircraft from various angles. The BCAS system was operated in the forced active plus passive mode. Air Traffic Control Radar Beacon System (ATCRBS) replies to the BCAS interrogator (forced active mode) and to a secondary surveillance radar, SSR (passive mode), were recorded and used as a measure of the adequacy of the air-to-air and ground-to-air radio links for some selected critical situations. The intruding general aviation aircraft was equipped with top- and bottom-mounted ATCRBS antennas (with independent transponders) during one series of encounters. The second series of encounters was flown with an aircraft equipped with a single bottom-mounted transponder antenna. (Author)
