Evaluation of Transponder Antenna Coverage/ATCRBS Performance during Simulated Flights of Aircraft.

摘要

A computer model was used to analyze the effect of aircraft orientation on the performance of the Air Traffic Control Radar Beacon System (ATCRBS). Flights by Cessna 150, Boeing 727, Boeing 747 and F-4H aircraft over a common flight route out of La Guardia Airport were simulated. Transponder/antenna performance for various aircraft attitudes and locations along the flight path was analyzed with respect to interrogators located at JFK airport. This performance was compared to a transponder having ideal, omni-directional antenna coverage to illustrate the degree to which the combination of aircraft orientation and transponder antenna pattern may affect ATCRBS performance.
