摘要
根据平面电磁波在具有不同物理性质的介质分界面发生的反射规律,利用雷达实测信号的幅值信息,实现了公路层介电常数的自动计算。并根据物理模型实验结果,建立了沥青材料含水率与介电常数之间的数学关系模型。利用这二项技术可以实现应用探地雷达技术检测沥青公路的含水状况。
Based on the EM wave reflection occurred at interface of media having different physical properties, the relative dielectric constant of road pavement could be automatically calculated by using amplitudes of radar signals. And based on the physical modeling results, a mathematical model describing the relation between moisture and dielectric constant was set up. Pavement water content of bituminous road could thus be detected by using ground penetrating radar.
