无人机激光跟踪与无线供能系统

为了解决无人机工作时间短、续航能力差的问题，采用激光无线供能的方式给无人机进行续航，提出并设计了一套基于跟踪、捕获、瞄准的激光无线能量供给系统，并进行了理论分析，同时在外场200m范围内进行了无人机激光无线供能实验。结果表明，该系统整体光电转换效率约为12%，跟踪精度优于500μrad。该研究为激光跟踪与无线供能技术用于小型航天飞行器提供了参考。

Laser tracking and wireless power supply system for unmanned aerial vehicles

In order to solve the problem of short working time and poor endurance of unmanned aerial vehicles (UAV), laser wireless power supply was used in UAV. A set of laser wireless energy supply system based on tracking, capturing and aiming was proposed and designed. After theoretical analysis, the experiment of UAV laser wireless power supply was carried out in the outfield of 200m. The results show that, the overall photoelectric conversion efficiency of the system is about 12%, and the tracking accuracy is better than 500μrad. The study provides a reference for the use of laser tracking and wireless energy supply technology for small space spacecrafts.
