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,...

What is ground penetrating radar? - Ground penetrating radar GPR is a non-destructive geophysical survey method that can detect subsurface features without drilling, probing, or digging. GeoModel, Inc. conducts ground penetrating radar GPR surveys nati
Penetrating Radar or WPR) on freshwater has a sporadic history in publications due to some successes (see below) and probably unpublished failures – both of which are considered here. This review was prompted by attendees at a number of conferences and training events, asking how best to ...

Ground-penetrating radar (GPR, also referred to as ground-probing radar, surface-penetrating radar, subsurface radar, georadar or impulse radar) is a noninvasive geophysical technique that detects electrical discontinuities in the shallow subsurface (<50 m). It does this by generation, transmission,...
