ABSTRACT:
A system for detecting, monitoring the movements of, and controlling the travel of aircraft and other vehicles on an airport surface. A series of small low-powered radar transmit-receive devices, each having a limited range, is disposed essentially in a line along alternate and opposite sides of a runway, ramp or taxiway. Control pulses at a system PRF travelling down the inter-connecting cables serve to cause the individual radars to "blink" in sequence in accordance with the inherent delay in the inter-connecting cable. Frequency separation is used to prevent false indications due to transmit-receive inter-action among the individual miniature radars. The system is adapted to data presentation in accordance with standard radar display techniques, or alternatively, a display is provided on a synthesized map of the airport. A pulse delay discriminator arrangement provides for discrete lateral position control. Means are also shown for televising the ground display to a vehicle on the surface and for providing discrete information such as a STOP order, etc.
