Skip-glide target tracking based on improved Jerk model

Aiming at the problem of tracking skip-glide targets using radar, this paper proposes an Unscented Kalman Filter (UKF) tracking algorithm based on the improved Jerk model.Aiming at the estimation error introduced by the artificial olea europaea montra preset acceleration variance and Jerk frequency of the conventional Jerk algorithm, this method ca
