Abstract

Kalman filter which is used extensively in target tracking13; applications performs optimally when the model describing the target motion is specified correctly. In tracking applications, for targets moving with constant velocity (CV), the state model includes the first derivative of position and for targets moving with constant acceleration (CA) it includes second derivative of positionill. Models with second order derivatives are preferred for tracking maneuvering targets and referred to as acceleration models12'31. However, for highly maneuvering targets, it is seeni41 that the tracking13; performance of acceleration model is not very accurate since under large maneuver conditions, higher order derivatives of position become significant. Hence, models which include third order derivative of the target position, termed constant jerk (CJ) models are preferred for tracking targets executing evasive maneuvers141.
