通过选取LEO区域中两种典型材料的小尺度空间碎片, 分别建立了相应的强激光与靶材的冲量耦合模型, 研究了高能脉冲激光与靶材作用下碎片速度的变化规律。在此基础上建立了激光辐照作用下小尺度空间碎片的变轨模型。通过仿真分析, 对假定功率激光器作用下两种典型材料空间碎片轨道参数的变化规律进行了数值模拟, 并讨论分析了碎片自旋角速率及不同功率的激光器对碎片清理效能的影响规律。研究结果表明, 在假定功率的天基平台激光器作用下能在一个飞行周期内辐照两种典型材料碎片达到降轨清除效果, 为天基平台激光清除空间碎片技术的应用提供了必要的理论基础。

Two typical materials of small scale space debris in LEO were selected. On this basis, corresponding laser ablation impulse coupling models were established respectively. The velocity variation of the space debris irradiated by high-power pulsed laser was analyzed, and the orbit transfer of the small scale space debris irradiated by laser was modeled and investigated. The variations of the orbital parameters of the space debris orbit under the irradiation of laser with assumed power were simulated and analyzed, and the influence rules of the spinning angular velocity and laser with different power on debris removal efficiency were analyzed and discussed. The simulation results show that the space-based laser of assumed power can complete the mission of removing two typical materials of debris successfully by irradiating in one cycle of flight, which provides necessary theoretical basis for the application of space debris removal by using space-based laser.
