小尺度空间碎片天基激光清除过程研究

摘要

选取LEO区域中典型材料的小尺度空间碎片,建立了相应的靶材模型,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,对高能脉冲激光作用下典型空间碎片轨道参数的变化规律进行了数值模拟.研究结果表明,设定的天基平台激光站能在一个飞行周期内辐照典型材料碎片达到降轨清除的目的,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.%Corresponding target model was set up by selecting typical materials of small scale space debris in LEO.The velocity variation of the space debris ablated by high-power pulsed laser was analyzed and the orbital transfer model of small scale space debris irradiated by laser was built and studied,and the change rules of the orbital parameters of the space debris orbit under the irradiation of high-power pulsed laser were simulated and analyzed.The simulation results show that,the assumed space-based laser system can remove typical material debris successfully in one cycle of flight.It provides necessary theoretical basis for the further application of space debris removal by using space-based laser.
