Abstract:

To improve the performance of maneuver detection for space non-cooperative targets with mall pulse orbit based on existed approaches, an orbit maneuver detection algorithm using angle-only measurements by passive optical camera is developed, where the relative angular momentum is introduced as a new characteristic to be measured. Firstly, the relative dynamics model based on Clohessy-Wiltshire equations and the relative line-of-sight measurement model when the camera is installed off the center of mass are established in the orbit coordinate system. Then, the definition of relative angular momentum is given and the benefit of this characteristic as the test parameter to detect maneuver is analyzed quantitatively. Next, the framework of the maneuver detection algorithm based on variance ratio of double sliding window is designed. Finally, simulations are conducted to verify the effectiveness and performance of the proposed algorithm. The simulation results show that the proposed algorithm can realize the fast orbit maneuver detection to the near-circular orbit target and the error is within 60 s.
