TARGET MANEUVER DETECTION
First Claim
1. A method for determining whether a moving target is maneuvering, comprising:
- determining an expected motion for the target assuming the target is not maneuvering;
determining an upper bound and a lower bound for the expected motion; and
determining whether the actual motion exceeds at least one of the upper and lower bounds of the expected motion.

Abstract
The present invention includes, in its various aspects and embodiments, a method and apparatus for determining whether a moving target is maneuvering. The method comprises determining an expected motion for the target assuming the target is not maneuvering; determining an upper bound and a lower bound for the expected motion; and determining whether the actual motion exceeds at least one of the upper and lower bounds of the expected motion. In one aspect, the apparatus is a program storage medium encoded with instructions that, when executed by a computing apparatus, perform such a method. In another aspect, the apparatus is a computing apparatus programmed to perform such a method.
