Patent ID: 7420501

Claim:
A method of correlating radar position data with target identification data comprising the steps of: using radar to determine radar position data of a first target; transmitting a signal from a first transceiver of known location to a plurality of targets, including the first target; receiving reply signals at the first transceiver from the plurality of targets, each reply signal including identification data about the respective target; using the transmitted signal from the first transceiver and the reply signals to calculate a first round trip delay value for each of the plurality of targets; using the first round trip delay value for each target to calculate a range of each target from the first transceiver; establishing a first range window for each target relative to the first transceiver, said first range window being defined as a range tolerance centered around the calculated range based on the first round trip delay value; using the radar position data of the first target to calculate a distance between the first target and the first transceiver; comparing the calculated distance with the first range windows for the targets to select a first range window that encompasses the calculated distance; and correlating the identification data from the target that corresponds to the selected first range window with the radar position data of the first target.
