Abstract:

Aiming at imaging satellite mission planned for marine maneuvering target, a satellite constellation for maneuvering target in ocean area searching and monitoring is designed. Firstly, according to the characteristics of maneuvering target search task, a satellite image stitching search strategy considering spatio-temporal constraints was established. Secondly, according to the established maneuvering target search strategy, a high time resolution networking constellation configuration was designed. Finally, a robust model was constructed based on minimizing the side pendulum angle and the task observation time of the networking satellite as  the optimization target. The simulation results demonstrate that the satellite constellation can effectively monitor the target area, providing the support method for maneuvering target regional surveillance task.

Key words: regional surveillance, maritime maneuvering target, multi-strip stitching, satellite constellation design
