探地雷达(Ground−Penetrating Radar)通过向地下发射高频电磁波,然后接收从地下物体反射回来的电磁波来探测和定位近地表面处的地下物体.天线和探测器直接放在地面上的同一位置.角频率ω沿z方向传播的线偏振平面电磁波的电场可由下式表示:E=E0e−αzcos(ωt−βz))(*)其中E0为常数,α为衰减常数,β为波数,...
Forward modelingRoad structure is composed of different pavement materials. These materials contain a large number of particles and pores with different sizes, shapes, dielectric properties and spatial locations, which determines the electromagnetic properties of roads. These feature multi-scale and ...
