Abstract

The miniaturization of high-power laser system, especially the space-based laser system, poses a great threat to the national space security. In this paper, facing the space-based offensive and defensive operations in the future, the features and damaging modes of high-power laser system as well as the conventional laser protection technologies of spacecraft are analyzed. On this basis, a novel multilayer protective armor is proposed, which can significantly improve the survivability of spacecraft under the high-power laser beam. Furthermore, a physical-informed deep surrogate model for the temperature field reconstruction is also studied to achieve the laser spots detection within second, helping the on-orbit spacecraft to implement the evasive maneuver. The results of this work can help enhance national space safety level.
