TBTGPR-MIMO 3D GPR array system is a controller-antenna integrated multiple-input and multiple-output detecting system, the military grade anti-vibration design features it more convenient and flexible for using, even in complex environments the radar system still work stably and reliably. The perfect channel uniformity guarantees the good imaging effect, and features convenient for data processing and imaging judgement and location. It can be widely used in imaging detection of airport, tunnel, highway, water conservancy, bridge, utility engineering, military and archaeology.


TBTGPR Series 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.


1. Radar controller & antenna array are integrated in small size & light weight, features low power consumption;

2. Universal network cable is used for data transmission, it is simple, common and convenient;

3. Compatible external DC power supply 10V-18V;

4. Single-frequency array and multi-frequency array fully guarantees various detecting requirements;

5. MIMO array antenna system with higher antenna density and higher integration grants good imaging effect;

6. Fast detecting process and data acquisition, better uniformity of channels and profile data with even intervals;

7. The real-time acquisition software can be installed in laptops or other handheld terminals for convenient carry and use;

8. The real-time acquisition software is with basic functions of filtering, removing zero offset, background eliminate and real-time 3D slice imaging;

9. System intelligently adjust radar parameters no need manual operation;

10. Real-time vehicle speed display, over speeding alarm and weak GPS signal alarm;

11. Data replay function allows completely restoring the acquisition process;

12. Real-time display the slicing profile at specified depth on the detection pathway, the detection result is very clear;

13. According to GPS position information, automatically display GPS locus of stored data, correct the predicted survey line according to locus, to achieve full coverage detection;

14. System can make interpolation for the uncovered areas between survey lines to form a full-coverage data, then output a panorama image.

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;
