Abstract
A method based on digital parallel system for imaging scheduling is proposed in this paper. Firstly, the architecture of digital parallel system is designed, and the detailed implementation process of imaging scheduling is given. Secondly, the digital twin satellite and ultra-real-time simulation environment are established, and the feasible solution set of imaging sequence meeting various constraints is determined through ultra-real-time simulation. Then, taking the revisit-time of target point as the performance index, the optimization problem of imaging scheduling is constructed. By solving the optimization problem, the imaging scheduling solution with the highest revisit frequency of multiple target points is obtained. Finally, a simulation case of imaging scheduling is given. The simulation result illustrates the feasibility of digital parallel system and the effectiveness of the method.
