Abstract
An air vehicle landing/takeoff area mapping system includes a plurality of transmitters located in the landing/takeoff area with each transmitter propagating a signal having a signal frequency indicative of the transmitter location. A receiver is located on the air vehicle and is capable of scanning the landing/takeoff area. The receiver processes a received transmitter signal to produce an output based on the received transmitter signal frequency. Control logic processes a sequence of receiver outputs to produce an image of the landing/takeoff area on a display device located within the air vehicle to assist a pilot during landings and takeoffs of the air vehicle under either clear or inclement weather conditions and/or either day time or night time visibility.
