An adaptive-gain alpha-beta tracker combined with three-dimentional circular prediction using estimation of the plane state

چکیده
In tracking systems using phased array antenna, the adaptive-gain CX-P tracker combined with circular prediction has been proposed for maneuvering targets. However, tracking quality of the circular prediction filter degrades for highly maneuvering targets that continue to change the turning plane, since the circular prediction is calculated on the assumption that a target flies on the same plane of previous three measured positions. In this paper, we extend the circular prediction to three-dimentional space and propose the adaptivegain LX-/~ tracker combined with three-dimentional cir: cular prediction using estimation of the plane state to improve tracking quality.
