Tracking and Identification of a Maneuvering Reentry Vehicle

A igh t model for a maneuvering reentry vehicle was developed for implementation in a bank of extended Kalman lters regulated by a gating network. The system was applied to the tracking and identication at high altitude of reentering spiraling objects accompanied by decoys. The object is being tracked at high altitude by three ground radars providing a variety of measurements which are treated in parallel by two lters, one being an expert tuned for the real target and the other tuned for the decoy. Experiments show that the regulated bank can rapidly correctly identify the object as being the real target.
