比较了超声波、无源红外线、激光雷达、连续波雷达、脉冲雷达、电容式距离传感器及视频成像系统的主要参数 ;讨论了追尾碰撞报警 /避免系统对距离探测技术的限制、要求及其在实际应用时所受的主要影响因素。结果表明激光雷达、连续波雷达、单脉冲雷达及视频成像距离探测技术可应用于追尾碰撞报警 /避免系统中。
The main parameters of ultrasonic, passive infrared, laser radar, continuous wave radar, pulse radar, capacitive distance sensor and video imaging system are compared. The limitations and requirements of rear-end collision warning / avoidance system on distance detection technology are discussed. Application of the main factors affected. The results show that lidar, CW radar, monopulse radar and video imaging distance detection technology can be applied to rear-end collision warning / avoidance system.
