1. A method of locating a target, comprising:

  • determining, with a sensor, a sensor location of the sensor;

    receiving, by the sensor, a transmission from a beacon, the beacon comprising;

    a location device operable to determine the beacon location of the beacon, andone or more transmitters operable to transmit the beacon location to the sensor,wherein the transmission comprises the beacon location;

    measuring, by the sensor, one or more location attributes of the beacon;

    determining, by the sensor, a target location of a target, wherein the sensor;

    performs a target location measurement by sending and receiving reflected radiation and without receiving a transmission from the target,calculates a correction factor from a difference in the measured one or more location attributes of the beacon and the beacon location as transmitted to the sensor by the beacon, andapplies the correction factor to the target location measurement to obtain a corrected target location measurement, wherein the target location, the sensor location, and the beacon location are distinct from one another.
