基于理论计算和室内试验方法,研究了温度和湿度变化分别对路面雷达检测精度的影响,研究结果表明,在温差较大地区,温度变化可引起路面雷达测距系统产生约0.3%～0.5%的误差;路面材料含水量的变化可引起路面雷达测厚检测结果约10%～15%的误差。针对温度和温度对路面雷达检测精度的产生影响的原理,给出了误差消除的的应对措施,以期对提高路面雷达的检测精度有所借鉴。
Based on theoretical calculation and laboratory test, the influence of temperature and humidity on the detection accuracy of pavement radar was studied respectively. The results show that the temperature variation in the large temperature difference can cause about 0.3% ~ 0.5% Error; Pavement material moisture content changes can cause road surface roughness measurement results of about 10% ~ 15% error. Aiming at the principle that the temperature and temperature affect the detection accuracy of the road surface radar, the countermeasures of error elimination are given in order to learn from the improvement of the detection accuracy of the road surface radar.
