摘要
由于路基路面异常体病害探地雷达探测中存在的诸多问题,主要针对地下散射波进行讨论,认识了异常"点元"的电磁波响应特征,通过数值模拟和物理模拟结果来揭示电磁波的叠加原理,只有当异常体上的某个"点元"所形成的散射波被位于其正上方的雷达仪器以首波的形式记录时,该记录点所对应的水平位置才是该"点元"所在的实际位置。
Because of subgrade and pavement penetrating radar diseases in a number of issues, mainly for underground scattering wave discussion, understanding the abnormal "point element " of the electromagnetic response characteristics, the numerical simulation and physical simulation results reveal the electromagnetic wave superposition principle, only if the anomaly of " point element "formed by the scattering wave was located above the radar equipment is the first wave in the form of records, the records at the level corresponding to the location is the" point element" of the actual position.
