ABSTRACT:
In an embodiment, an apparatus includes a detector, direction finder, receiver, and range finder. The detector is operable to detect a target, and the direction finder is operable to determine a first direction to the target from the apparatus. The receiver is operable to receive a second direction to the target from a remote object, and the range finder is operable to determine from the first and second directions a range of the target from the apparatus. For example, the apparatus may be a first fighter jet, and the remote object may be a second fighter jet. By using directional information from both the first and second jets, a computer system onboard the first jet may compute a range to the target from the first jet more quickly and more accurately than by using directional information from only the first jet.
