Three dimensional radar testing and analysis of road collapse accidents

The ground penetrating radar host emits wideband short pulse electromagnetic waves underground through the transmitting antenna. When the electromagnetic waves encounter underground formations or targets with electrical differences, they will be reflected, and the reflected waves will return to the ground and be received by the receiving antenna. When high-frequency electromagnetic waves propagate in a medium, their propagation path, electromagnetic field strength, and waveform will vary with the electrical characteristics and geometric shape of the medium they pass through.

Therefore, by collecting, processing, and analyzing time-domain electromagnetic wave waveforms, the spatial position and structure of underground interfaces or geological bodies can be determined.

The currently used ground penetrating radar mainly includes two types: two-dimensional ground penetrating radar and three-dimensional ground penetrating radar.

By using digital step frequency technology, different frequency ranges can be adopted for various applications, and the entire spectrum can be controlled through parameter settings in the acquisition software to optimize the relationship between detection depth and radar system resolution, thereby obtaining the best detection target image quality; At the same time, GeoScope utilizes electronic scanning antenna array technology, which enables fast and accurate 3D exploration, achieving true 3D detection; GeoScope acquisition software can display real-time 3D images and is currently the first ground penetrating radar system on the market to achieve on-site 3D imaging.

Excellent measurement results are perfectly combined with * shielding technology.

The GCB series antenna represents the ground coupled GPR antenna technology currently available in the market for testing performance. These shielded ground penetrating radar antennas can provide perfect performance and results even when used anywhere in the world with electromagnetic pollution. By implementing complex modeling and electrical design solutions, we assure you that each GCB antenna is lightweight and compact, replacing current solutions.

Multiple types of full range antennas can be connected, such as ground coupled antennas, air coupled antennas, borehole antennas, and multi frequency combination antennas. Used for tunnel advance prediction, tunnel lining, steel reinforcement, concrete structure detection, underground pipeline detection, shallow geological, hydrological, archaeological, environmental and other surveys.
