Abstract :
Although simple to implement, a bearing-only tracker using an extended Kalman filter mounted on a stationary sensor platform has not proven serviceable. This paper provides a fixed-base, image-enhanced, recursive filter that performs well against a maneuvering target. Tight cover intervals are generated and compared with a well-known upper bound. The case of an in-coming missile is used as an example.
