现有的无人机探测通常采用以雷达扫描为主，辅以其他传感器探测的方式。但是，目前使用雷达探测的成本较高，而激光器作为一种低成本、低功耗的器件已受到人们广泛关注。以激光为载体，结合无线光通信中的捕获、瞄准、跟踪(APT)系统，设计并实现了一种基于激光探测技术的无人机扫描定位系统，并以气球模拟无人机目标的测试方式，测试了该系统的定位精度和效率。扫描试验结果表明：在激光发射器平均功率小于40mW的情况下，该系统对目标的捕获定位能达到较高的精度，误差在5%以内，最大可探测范围为45m。

Existing unmanned aerial vehicle (UAV) detection mainly applies radar scanning as the main detection method and other sensors as the supplement, but the cost of radar is relatively high. As the device with low cost and low power, the laser has received widespread attention. In this paper, using the laser as a carrier and combining with the acquisition, pointing, tracking (APT) system in wireless optical communication, a UAV scanning positioning system based on laser detection technology was designed and implemented. The positioning accuracy of the system was tested by using a balloon test method. The scanning test results show that when the average power of the laser transmitter is less than 40mW, the target can be captured and positioned with a high accuracy with an error of lower than 5%, and the maximum detectable range is 45m.
