Abstract:

The need for collaborative observation of multi-satellite regional targets is becoming increasingly complex in engineering applications. However, due to differences in geological structure and character activities in a target to be observed, the importance of the targets to be observed in the target is different, the corresponding observed returns are different. How to arrange the observation program to maximize the total benefit of the observation is a problem that needs to be solved in the case of limited resources. In this paper, considering the actual situation of unequal internal observation income of regional targets, a multi-satellite scheduling optimization model with variable internal income of regional targets is established. The dynamic stripe segmentation method (DSSM) is designed and proposed based on weights. The weight priority strategy heuristic (WPSH) and the random neighborhood local search (RNLS) algorithm maximize the observation benefit corresponding to the solution result. Finally, the simulation experiment proves that the DSSM algorithm improves the observation yield by about 19% and the coverage rate by about 22%. The RNLS algorithm is about 4.5% higher than the WPSH algorithm, and the solution quality is stable.
