交通用雷达测速仪标定装置一直存在着不足,目前国内对该项目的研究还比较缺乏,利用非接触梳状光电式速度传感器检测被测车辆的速度,与雷达测速仪测得车速比对,从而达到对雷达测速仪进行标定的目的.同时根据光电传感器信号特点,研制出雷达测速标定装置信号调理电路.试验表明,该装置能达到预期的检定效果.“,”To resolve the problem of traffic speed measuring radar calibration, the research for speed measuring radar calibration is rarely in China now, non-contact comb shape photoelectric sensor was used to measure the speed of vehicles, compared to the speed got by speed measuring radar, then the radar calibrated. According to the character and principle of the comb shape photoelectric sensor, circuit used to process signals produced by the sensor was designed. The experiment results proved that this device can achieve the expectant effect.
