Problems solved by technology

[0003] At present, in the ground penetrating radar CT transmission detection experiment, due to the influence of the detection experimental conditions and operation methods, the operators often have inconsistencies between the radar data channel number and the detection position information when collecting the ground penetrating radar CT transmission data. The error directly leads to the reduction of CT inversion accuracy
At the same time, the movement of experimental operators will also bring electromagnetic wave interference, especially for high-frequency radar data, the data quality will be greatly affected

Abstract

The invention discloses an experiment device for ground penetrating radar CT (Computed Tomography) transmission detection. The device comprises a box body, an antenna moving driving system, a ground penetrating radar transmitting antenna, a ground penetrating radar receiving antenna, a radar host, and a base. The ground penetrating radar transmitting antenna and the ground penetrating radar receiving antenna are arranged on two sides of the box body, and are connected with the antenna moving driving system. The ground penetrating radar receiving antenna is connected with the radar host. The experiment device for ground penetrating radar CT transmission detection has the advantages that the antenna moving driving system can control the ground penetrating radar transmitting antenna and the ground penetrating radar receiving antenna to automatically complete data acquisition according to a preset path, so that accurate recordings of data track numbers and detection position information are achieved, and data acquisition errors are reduced; and automatic acquisition of data can effectively reduce electromagnetic wave interference caused by operators, so that experiment operation flow is simplified.

Description

technical field [0001] The invention relates to the field of ground penetrating radar, in particular to a ground penetrating radar CT transmission detection experimental device. Background technique [0002] Ground-penetrating radar CT transmission detection technology is a fast, efficient and non-destructive detection geophysical detection method. During the ground-penetrating radar CT transmission detection experiment, the transmitting antenna and receiving antenna of the ground-penetrating radar are placed on the corresponding sides of the observation area. , the ground penetrating radar CT transmission detection experiment uses the ground penetrating radar transmitting antenna to transmit electromagnetic wave pulse signals, the ground penetrating radar receiving antenna receives the radar echo signals passing through the observation area, and then analyzes and processes the obtained data to obtain the observation area. Abnormal body distribution status. [0003] At pres...
