摘　　要：为了提高微型无人机(MUAV)的续航时间,基于二轴扫描振镜的工作原理,设计了一套激光对MUAV的远程实时跟瞄充电系统。系统采用硅光电池阵列作为光斑位置传感器,其信号经扫描跟踪算法处理后,在地面与MUAV间建立起无线数传反馈链路,控制二轴扫描振镜改变激光发射方向,实现激光束对MUAV的扫描与实时跟踪;同时硅光电池阵列也作为充电器件,实现对MUAV的实时充电。结果表明,当MUAV在高度为80m、直径50m圆形区域内以低于2m/s速率飞行时,可实现激光对MUAV的准确跟踪,跟瞄精度小于0.63mrad。该系统具有跟踪速度快、瞄准精度高的特点,为激光对移动目标的远程实时能量传输提供了一种有效的解决方案。In order to improve the endurance of the micro-unmanned aerial vehicle(MUAV),based on the working principle of the two-axis scanning galvanometer,a remote real-time laser tracking and pointing charging system for the MUAV was designed.In the system,a silicon photocell array was used as the spot position sensor.Firstly,the signal was processed through a scanning tracking algorithm,then a wireless data transmission feedback link was established between the ground and the MUAV,and the emission direction of a laser beam could be changed by controlling the two-axis scanning galvanometer.At the same time,the silicon photocell array was also used as a charging device to realize real-time charging of MUAV.The experimental test results show that when the MUAV flies at a speed of less than 2m/s in a circular area with a height of 80m and a diameter of 50m,the system can accurately track the MUAV with a tracking accuracy of less than 0.63mrad.It has the characteristics of fast tracking speed and high aiming accuracy.This research provides an effective solution for laser remote real-time energy transmission to moving targets.
