Image-enhanced tracking using a phased array radar
David D. Sworder, John E. Boyd, G.A. Clapp · 2002
A phased array radar is an effective tool for tracking agile targets at intermediate and close ranges. Even so, high maneuver rates may lead to unacceptable loss-of-lock rates unless the interdwell intervals are short. This paper shows that the interdwell interval can be extended, and estimation performance can be improved using an image-enhanced tracking algorithm. The geometry of the encounter is modeled explicitly, and the correlations between angular and translational errors are utilized to fashion an effective tracking algorithm.>
