摘要
为解决汽车激光雷达的相互干扰造成目标检测与跟踪性能的严重下降的问题,从空间、时间和调制频率等方面出发,研究脉冲方式和频率调制连续波方式激光雷达在道路环境中可能存在的各种干扰,通过仿真计算干扰发生的概率、分析干扰的特征,以及干扰对测量性能下降的影响。针对可能存在的干扰问题,指出使用伪随机码调制连续波激光器输出幅度的方式可以有效降低干扰发生的概率,保证激光雷达在道路环境中有效可靠地工作。
Mutual interference of vehicular laser radar causes serious performance reduction of target detection and tracking.From spatial,time and modulation frequency,various possible interference of lidars of pulse and frequency modulated continuous wave method in road environments are studied by simulation.The possibility of the interference is calculated,the features and performance reduction of the interference are analyzed.For the possible interference,using a method of pseudo random noise code to modulate the output amplitude of the continuous wave laser can effectively reduce the probability of interference and ensure the reliable operation of lidar in road environments.
