Patent ID: 8174433

Claim:
A method comprising: receiving a plurality of measurements in real time, the measurements comprising a plurality of radar measurements and a plurality of radar array orientation measurements, the radar measurements generated by a radar system tracking a target, the radar measurements indicating a location of the target, the radar array orientation measurements generated by a navigation system of the radar system, the radar array orientation measurements indicating an orientation of a radar array of the radar system; performing the following for a number of iterations to yield a plurality of state value sets for a state variable set, the state variable set comprising one or more measurement variables and one or more dynamic bias variables, a measurement variable associated with a measurement, a dynamic bias variable associated with bias of a measurement: updating a state value set according to the measurements to yield an updated state value set; and predicting a next state value set in accordance with the updated state value set; and determining an orbit path of the target from the state value sets in real time.
