A mathematical model representing the 1960 New York environment affecting Air Traffic Control Radar Beacon System capacity was developed to evaluate the effects of changes in system parameters. Computations were based on the geographical coordinates of existing ground stations and of a realistic pattern of air traffic. The combined effect of all stations on the reply rate from each aircraft was calculated. Interrogation efficiencies, averaged over a short time interval, were predicted for the basic system and for three side-lobe suppression techniques with various AOC reply-limit and transponder dead-time settings.
