Abstract : An Identification Friend or Foe (IFF) method and system are provided to detect (1) friendly ground-based vehicles, (2) each of the vehicle's unique identity, and (3) each of the vehicle's approximate position. A video image of an area of interest on the ground is generated from an aircraft. The video image is defined by a matrix of pixels. A range from the aircraft to a reference position within the area of interest is provided. The reference position is defined by known latitude, longitude and height within the area of interest and is further defined in the matrix of pixels by matrix coordinates. A coded signal is transmitted from a vehicle on the ground to uniquely identify the vehicle and identify the vehicle as friendly. The coded signal is also detectable as part of the video image when the coded signal is transmitted from the area of interest.
