The invention discloses a ground penetrating radar, and relates to the field of radio technologies. The ground penetrating radar comprises a control assembly, a communication assembly, an emission antenna and a reception antenna; the communication assembly comprises a signal processing module, an emission channel, a reception channel and an inhibition channel, the signal processing module is connected with the emission channel, the inhibition channel, the reception channel and the control assembly, the emission channel is connected with the emission antenna, the reception channel is connected with the reception antenna, and the output end of the inhibition channel is connected to the reception channel; and both emission signals emitted by the emission antenna and echo signals received by the reception antenna are continuous wave signals, the inhibition channel outputs inhibition signals to the reception channel, and the inhibition signals are used to eliminate direct waves and / or ground clutters in the received echo signals. The ground penetrating radar uses continuous waves for detection, detection energy is high, and detection is farther; the inhibition signals output by the inhibition channel are used to eliminate direct waves and / or ground clutters in the received echo signals, so that detection is more accurate.
Description
technical field [0001] The invention relates to the field of wireless technology, in particular to a ground penetrating radar. Background technique [0002] Ground-penetrating radar is also called ground-penetrating radar. It transmits electromagnetic waves to the ground through the transmitting antenna, and receives the electromagnetic waves reflected back to the ground through the receiving antenna. The distribution of underground media such as the spatial position, structure, shape, and burial depth of the underground media can be inferred according to the characteristics of the waveform, amplitude intensity, and time change of the received electromagnetic waves. [0003] At present, most of the commonly used ground penetrating radars use the pulse system model, that is, the ground penetrating radar conducts non-destructive detection of the underground medium by transmitting pulse waves underground. The precision is not high enough. Contents of the invention [0004] ...
