Abstract:

Aiming at the imaging requirements of new complex targets such as point-cluster and large-region targets, to improve utilization efficiency of satellite resources and complpete income of observation tasks, the imaging satellite mission planning model and algorithm for point-cluster and large-region targets are studied. Firstly, a unified decision model is constructed, and the stripe elongation rate is introduced as a decision variable to solve the problem of imaging representation of point-cluster targets. Constraints are considered including execution timing, power, sequestration, and conversion time. The task benefit model based on stripe elongation rate and grid coverage rate is established separately according to the characteristics of targets. Then, an adaptive wave-temperature control simulated annealing algorithm combined with tabu strategy is designed to provide adaptive and efficient intelligent model solving methods, which improves the global optimization ability through the wave-temperature control and internal-cycle-number update strategies, and enhances the local search ability by tabu strategy. Simulation experiments show that the model and algorithm can effectively improve the planning effect. The proposed algorithm and model are suitable for imaging satellite mission planning problems for point-cluster and large-region targets.

Key words: satellite mission planning, point-cluster target, large-region target, wave-temperature control, simulated annealing
