Abstract
The time interval between the pulses of an interrogation signals transmitted to aircraft in the vicinity of an airport is varied at will in accordance with air traffic conditions. The time interval under heavy traffic conditions may be varied from its nominal value as a function of the rate of response signals, the garbling rate thereof, or the decoding rate. The time interval may be controlled manually as a function of air traffic conditions displayed on a screen associated with the interrogator and receiver. By varying the time interval the percentage of responses to interrogation may be varied to optimize overall reception conditions and utilization of potentially available information.
