Description

Technical field [0001] The invention relates to the technical field of ground penetrating radar, in particular to a beam scanning ground penetrating radar system and an intelligent beam scanning detection method. Background technique [0002] The general ground penetrating radar uses a single antenna to transmit and receive. The ground penetrating radar advances along the survey line, radiates electromagnetic beams directly below it and receives echoes to achieve two-dimensional imaging results. The multi-channel ground penetrating radar is to place multiple transmitting antennas in parallel, and each antenna radiates electromagnetic beams directly below it. The array detection is realized by combining multiple antennas, and a master recording device is used to control each antenna. The collected data is arranged in a suitable way. Compared with single-antenna ground penetrating radar, this multi-channel technology increases the detection area covered by one measurement and impr...

AI Technical Summary

Problems solved by technology

Compared with single-antenna ground-penetrating radar, this multi-channel technology increases the detection area covered by one measurement, which improves the detection efficiency of ground-penetrating radar to a certain extent, but requires a wider array coverage, so that the array size is larger. up to several meters wide

[0003] The invention mainly aims at the low detection efficiency in the use process of ground penetrating radar, the array volume of array ground penetrating radar is large, the antenna function is single, the beam direction is fixed, and cannot be intelligently controlled, and the resolution cannot be adjusted during the detection process.

In addition, due to the complexity of the detection environment and the diversity of detection targets, traditional ground penetrating radar needs to replace the antenna according to different detection environments, or manually modify the channel and other parameter settings according to the detection situation, which cannot meet the diverse detection needs
