  • Main Specifications
  • Accessories

TBTGPR-40 multi-channel GPR system is mainly used for highway related detection, the controller with channel-parallel designing allows each channel to work independent and simultaneously, and collects 4 channels data (Max.up to ~12 channels) to achieve the best detection performance and efficiency. 

The controller is compatible with all TBTGPR series antennas with center frequency range from 35MHz to 2500MHz. The system can be flexibly configured to maximumly meet the actual needs of engineering inspection and detection.


TBTGPR-40 system Application:

City road and airport runway quality inspection

City road subsurface cavities and disease detection

Utility pipeline detection

Tunnel and railway inspection 

Pavement asphalt layer thickness, structural layer thickness and disease detection

Highway structural layer thickness and roadbed disease detection



1, Channels work independent and simultaneously without mutual interference. It means several single-channel radars working at the same time (upper time-sharing control), which greatly improves the  detection efficiency.

2, Good flexibility and compatibility, channel numbers and antenna frequency can be freely selected.

3, The system automatically identify antenna and make parameter configuration.

4, The system saves both original data and in-field data.

5, Vehicle encoder and antenna encoder are optional.

6, Controller 2U structure designed with external terminals connection by serial port (RS232), RJ45, USB etc.

7, The antenna trailer is integrate designed with tire wheels, it can go forward, backward or turn other directions. The trailer is made with wear-resistance cover and bottom fully ensures the radars working safely at speed around 70KM/h.  The compact designed trailer size is 1960x1155x530mm.

GPR-40 Software Functions and features:

1) The 4-channel simultaneously acquisition and display in various optional modes such as tiling, cascading or one channel individually.

2) Various detecting methods available such as continuous measuring or distance trigger detecting methods.

3) Various data processing methods can be selected to highlight the signal characteristics of the detected target. 

4) Original data and in-field data are saved at the same time to avoid data invalidation caused by misoperation. 

5) The data format is fully compatible with GER general radar data format, GER2.0 software is used for data processing with powerful functions and friendly interface. 

6) The real-time acquisition software can be installed on laptops or other handheld terminals for convenient carry.
