High-speed imaging ultra-wideband ground penetrating radar vehicle

Abstract

The invention provides a high-speed imaging ultra-wideband ground penetrating radar vehicle. The high-speed imaging ultra-wideband ground penetrating radar vehicle comprises a construction vehicle and a high-speed imaging ultra-wideband ground penetrating radar system. The high-speed imaging ultra-wideband ground penetrating radar vehicle is characterized in that the high-speed imaging ultra-wideband ground penetrating radar system is a double-frequency-band and double-channel short pulse radar which is mounted on the rear half part of the construction vehicle; a pulse signal is sent by an emission antenna and received through a receiving antenna; a signal processing and display terminal is under a multi-processor mode; data streams are stored in a hard disk of a computer; an antenna of the radar system comprises the emission antenna and the receiving antenna which are arranged in parallel in an antenna mounting box at the tail part of the construction vehicle by an air coupling mounting manner; the emission antenna and the receiving antenna are waveguide ducts composed of two conductors; an insulator is arranged between the two conductors. The high-speed imaging ultra-wideband ground penetrating radar vehicle has the advantage that a road and a bridge can be effectively detected while running at a high speed on the premise that the traffic is not influenced.

Description

technical field [0001] The invention relates to a detection radar, in particular to a high-speed imaging ultra-wideband ground-penetrating radar vehicle. Background technique [0002] The use of non-destructive testing technology to identify the characteristics of underground structures is widely used in more and more fields, such as oil and gas exploration, geological exploration, pipeline monitoring, construction engineering, etc. The application of ground penetrating radar in the detection of roads and bridges brings many conveniences to the daily maintenance and condition assessment of roads and bridges. Since the high-speed imaging UWB GPR under high-speed motion can ensure excellent spatial resolution under high-speed motion, the GPR can be placed in an engineering vehicle to complete the detection and evaluation of roads and bridges at normal speeds without impact on traffic. [0003] According to the installation form of the radar, GPR can be divided into ground-so...

Problems solved by technology

In order to prevent the antenna from colliding with the ground and being damaged during the detection process, the permissible moving speed of the ground source ground penetrating radar is very low

The antenna of the air-coupled ground penetrating radar is relatively high from the ground. At present, most ground penetrating radars use low-speed equivalent time sampling in the application of data acquisition units, resulting in low sampling speed and impossible to achieve high-speed movement. Effective sampling under
