TBTGPR-20 radar uses high-frequency electromagnetic (EM) waves (from low to high frequency) to acquire subsurface information. TBTGPR detects changes in EM properties (dielectric permittivity, conductivity, and magnetic permeability), that in a geologic setting, are a function of soil and rock material, water content, and bulk density. Data are normally acquired using antennas placed on the ground surface or in borehole or in air. The transmitting antenna radiates EM waves that propagate in the subsurface and reflect from boundaries at which there are EM property contrasts. The receiving GPR antenna records the reflected waves over a selectable time range. The depths to the reflecting interfaces are calculated from the arrival times in the GPR data if the EM propagation velocity in the subsurface can be estimated or measured.

Antenna types | Center frequency | Pulse width | Depth range | Reference depth | Antenna Applications |
Ground coupling antenna | 200MHz | 5ns | 1~6m |
4m

600MHz | 1.6ns | 0~3m | 1.5m | Roadbed disease detection, Invert quality inspection, utility detection, Water conservancy and hydropower engineering, Geological survey | |
Important note: The penetrating depth of the antenna is tightly related to the conductivity of the medium, the higher the conductivity, the shallower the penetration depth of antenna. The penetration depth will drop sharply in wet clay. The above penetrating depth is under absolute condition of theorotical value. | |||||
