1. An RF tracking system for determining characteristics of at least one object in a local area, the system comprising:

  • (a) at least one remote spread spectrum radio transceiver, the at least one remote spread spectrum radio transceiver being coupled to the at least one object in the local area;

    (b) at least three tower spread spectrum radio transceivers being positioned proximate to the local area and the at least three spread spectrum radio transceivers transmitting signals to and receiving signals from the at least one remote spread spectrum radio transceiver;

    (c) a signal processor coupled to the at least three tower spread spectrum radio transceivers, the signal processor processing signal data received from the at least three tower spread spectrum radio transceivers;

    (d) a database engine in communication with the signal processor, the database engine storing in and retrieving from a database the signal data and biographical data relating to the at least one object; and

    (e) a processor coupled to the database engine, the processor determining the characteristics of the at least one object based, at least in part, on the signal data and the biographical data.
