A JERK MODEL FOR TRACKING HIGHLY MANEUVERING TARGETS

A model of target motion in three-dimensional space that includes posi tion derivatives up to the third order is developed. Compared with ava ilable models, which include terms at the most up to the second deriva tive, the model introduced in this work, called the jerk model, can mo re accurately describe agile target maneuvers which are likely to cont ain significant higher order derivatives. A compatible 4-state Kalman filter to perform tracking in conjunction with the jerk model is also presented, and an initialization procedure for the filter is provided. The improved performance of the jerk model over a lower order model i s illustrated through numerical simulation.
