摘要
激光雷达间的相互干扰是影响无人驾驶安全的核心问题之一。本文提出了一种光跳频(LFH)车载激光雷达系统及其相关测距方法,并通过仿真与实验分析了该LFH激光雷达在不同干扰条件下的抗干扰性能。结果表明,基于相关检测的LFH激光雷达能有效抵抗不同数量和强度的同类型LFH、脉冲、调频连续波和连续波激光雷达的干扰,且在不同类型干扰实验下的测距相对误差小于等于1.5%。这表明LFH激光雷达具备较好的抗干扰能力。
Mutual interference between LiDARs is a critical problem that affects the safety of driverless cars.In this paper,a vehicle-mounted,light frequency-hopping(LFH)LiDAR system and its related ranging method are proposed.The anti-interference performance of the LFH LiDAR is analyzed under different interference conditions by simulations and experiments.The results show that the LFH LiDAR based on correlation detection can effectively resist the interference from the same type of LFH,pulse,frequency-modulated continuous wave,and continuous-wave LiDAR in different quantity and intensity cases.In the experiment involving different types of interferences,the relative error of the detection range is less than or equal to 1.5%.It indicates that the LFH LiDAR has reliable anti-interference performance.
