Three-dimensional target tracking strategy based on guidance laws and optimal information fusion

Abstract

This paper presents a method for pursuer to track a moving target in a three-dimensional space. The method is based on the guidance laws combined with the kinematics equations of the pursuer and the target. The maneuvers of the target are prior unknown to the pursuer. Guidance laws used for tracking are the deviated pursuit and the proportional navigation, and the method presents a family of navigation laws resulting in a rich behavior for different parameters. For the three-dimensional scenario, two cases-not presenting interference and presenting interference are considered. In the absence of interference, the control strategy is proposed to implement the problem of tracking. In the presence of interference, an optimal information fusion Kalman filter weighted by scalars and guidance laws are combined to improve the trajectory tracking precision, and the combination can enrich the application range of information fusion and guidance laws. Simulations are conducted to demonstrate the effectiveness and reliability of the proposed control strategy.

End-to-end active non-cooperative target tracking of free-floating space manipulators

“…This method of target tracking is called active object tracking (AOT) (Li et al, 2020; Luo et al, 2018). However, current research on AOT is mainly focused on mobile robots (Cardenas et al, 2021; Cortés-Pérez and Torres-Méndez, 2021; Deutsch et al, 2005; Luo et al, 2019; Xi et al, 2021) or unmanned vehicles (Chang et al, 2020; Dong et al, 2021; Lin et al, 2022). Due to the widespread usage of space manipulators and the importance of AOT in non-cooperative target relative tasks, this article will investigate the active non-cooperative target tracking of FFSM.…”
