The antenna of underground detection radar is the core signal component of the ground detection radar system, with the core function of directional transmission and reception of high-frequency electromagnetic waves to achieve precise detection and imaging of underground media.
1. Directional transmission of detection signals: Match antennas of different frequencies according to detection requirements, convert the electrical signals generated by the radar host into high-frequency electromagnetic waves for directional propagation, and penetrate underground media such as soil, concrete, and rocks; High frequency antennas (hundreds of MHz~several GHz) are suitable for shallow high-precision detection, while low-frequency antennas (tens of MHz) are suitable for deep and large depth detection.
2. Receive underground reflected echoes: Capture the electromagnetic wave echoes reflected by media with electrical differences underground (such as pipelines, cavities, aquifers, archaeological sites), convert analog signals into digital signals that can be processed by the host, and transmit them to the main control unit for analysis.
3. Optimize signal transmission quality: Reduce signal loss through impedance matching design, and use structures such as beamforming and polarization adaptation (vertical/horizontal polarization) to concentrate the direction of electromagnetic wave propagation, suppress environmental clutter interference, and improve detection signal-to-noise ratio.
4. Adapt to multi scene detection: A single antenna can achieve single point scanning detection, and multiple array antennas can support 3D continuous scanning imaging; Ground coupled antennas are suitable for conventional surface detection, while dedicated antennas can be adapted to special scenarios such as underwater and tunnel environments.
Attention: When using underground detection radar antennas, do not aim the transmission port at the human eye or exposed skin area for a long time. Strictly follow the official operating specifications of the equipment to avoid potential high-frequency radiation effects.
