Automatic quick measuring system for common midpoint ground penetrating radar data

Abstract

The invention discloses an automatic quick measuring system for common midpoint ground penetrating radar data and relates to ground penetrating radar. The automatic quick measuring system is provided with an automatic measuring device for the common midpoint ground penetrating radar data, a computer and a radar host, wherein the measuring device is provided with driving nuts, a left screw rod, a right screw rod, a pipe coupling, a ground penetrating radar transmitting antenna, a ground penetrating radar receiving antenna and a stepper motor; the stepper motor is arranged at one end of the left screw rod; the left screw rod and the right screw rod are connected by the pipe coupling; the transmitting antenna and the receiving antenna are fixed on the left screw rod and the right screw rod through the driving nuts; the computer is connected with the stepper motor and the radar host through data cables; the stepper motor and the radar motor are used for respectively and synchronously controlling position moving and radar data acquisition of the transmitting antenna and the receiving antenna; the stepper motor is used for controlling the positions of the transmitting antenna and the receiving antenna and enabling the transmitting antenna and the receiving antenna to move toward opposite directions at equal distance by driving the left and right screw rods; the radar host is used for controlling the transmitting antenna to radiate high-frequency electromagnetic waves toward underground media; reflection echo from an underground target is recorded by the receiving antenna.

Description

technical field [0001] The invention relates to ground-penetrating radar, in particular to an automatic and rapid measurement system for common center point ground-penetrating radar data. Background technique [0002] Ground penetrating radar (GPR) is a recognized near-surface geophysical method. In the past two decades, ground penetrating radar has achieved a series of research results in hardware development, data processing and imaging methods. , and has been successfully applied in the fields of underground detection, engineering structure quality inspection, environmental monitoring and archaeological exploration. Since GPR data interpretation requires certain professional knowledge, it is difficult for non-professional technicians to use it, which restricts its further application in some engineering fields. The development of some robust GPR quantitative characterization and inversion analysis techniques will be the key to the second leap of the GPR method. [0003]...

Problems solved by technology

Data collection takes a long time and is labor-intensive

In addition, the manual control of the antenna position will inevitably introduce errors to the offset of the receiving / transmitting antennas, which has been proved to be the main source of errors in the subsequent dielectric parameter inversion results
