摘　　要：为了探讨交通信息检测与处理技术课程的实验设置,通过对该课程的设置进行了简要介绍。结合雷达测速检测设备的原理,试验从两个方面进行设置：一是手持雷达测速仪的人员站立的位置与车辆行驶方向的夹角分别为0°~10°、10°~30°、30°~45°、45°~60°;二是设定人工测量速度长度1、3、6、8 m,共分析了16种组合情况下使用雷达测速仪测得的速度精度。陈述了实验设置的步骤,并对采集的数据进行了处理和分析,对各种组合情况下的误差进行了统计。结果表明,雷达测速的距离8 m,测量角度10°以内得到的数据精度最高。In order to explore the experiment setting of the traffic information detecting and processing,the course was introduced simply. Considering the theory of the radar speed detector,there are two aspects in the experiment. One is the angle between the site of the person holding the radar gun and the direction of the vehicle driving,and the angles are designed as 0°- 10°,10°- 30°,30°- 45°,45°- 60°. Another setting is the length of the speed of the manual,and the values are 1 m,3 m,6 m,8 m. There are 16 conditions that should be detected using the radar gun. The steps of the experiments are described detailed. It was proved that the length of 8 m and the angle below 10° are the most desirable experiment environment and can get the highest accuracy. The results can provide reference for the course＇s experiment setting and the radar facility＇s proper using.
