1. 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.
