Performance Analysis and Comparison for High Maneuver Target Track Based on Different Jerk Models

Abstract EN

The Jerk model is widely used for the track of the maneuvering targets.

Different Jerk model has its own state expression and is suitable to different track situation.

In this paper, four Jerk models commonly used in the maneuvering target track are advanced.

The performances of different Jerk models for target track with the state variables and the characters are compared.

The corresponding limit conditions in the practical applications are also analyzed.

Besides, the filter track is designed with UKF algorithm based on the four different models for the high-maneuvering target.

The simplified dynamic model is used to gain the standard trajectory with Runge-Kutta numerical integration method.

The mathematical simulations show that Jerk model with self-adaptive noise variance has the best robustness while other models may diverge when the initial error is much larger.

If the process noise level is much lower, the track accuracy for four Jerk models is similar and stationary in the steady track situation, but it will be descended greatly in the much highly maneuvering situation.
