Description

Technical Field

[0001] The present invention relates to the technical field of geological radar, and in particular to a mobile dam detection device based on geological radar. Background Art

[0002] Ground-Penetrating Radar (GPR) is a non-destructive detection technology that detects the location, shape and depth of underground objects by emitting high-frequency (usually 10 to 1000 MHz) electromagnetic wave pulses into the ground and receiving the signals reflected by these pulses at different electrical interfaces underground. This method is often used in archaeology, geological exploration, road inspection, urban infrastructure investigation and other fields because it can obtain information about underground structures without digging the ground.

[0003] A geological radar system usually consists of a transmitting antenna and a receiving antenna, and sometimes these two functions may be integrated into one antenna. When electromagnetic waves encounter the boundary of materials with different dielectric constants, part of the energy is reflected back to the ground and captured by the receiving antenna. By analyzing the time delay and other characteristics of the reflected signal, an image of the underground structure can be constructed.

[0004] Geological radar is now widely used in the field of geological exploration. It plays a very important role in the detection of dams. Geological radar can effectively identify cracks or holes in dams. These defects may cause water leakage, which in turn affects the overall performance of the dam.
