GPR Ground Penetrating Radar
Instruction
Ground penetrating radar (hereinafter referred to as the GPR) Also called geological radar. It is used to determine
the distribution of underground medium by the radio waves with frequency 1M to 1000MHz.
The theory of it is launching high frequency electromagnetic wave into ground, and receiving the reflected the electromagnetic waves. Determine the position,structure, form and buried depth According to the waveforms,
strength and the change of time
Field
GPR can be used to test all kinds of materials, such as rock, dirt and gravel, and artificial materials (concrete,
brick, the asphalt etc). It is used to determine the position of metallic and non-metallic pipe, sewers, cables, cable pipe, holes,reinforced concrete , etc. It also can detect the different rock
depth and thickness.
Main use:
The buried depth of bedrock detection, ground water detect, the fluviolacustrine profile, the ancient riverbed detection, Mineral exploration. metal and non-metal detection,Road quality detection,Underground waste survey, and so on.
