Embodiment Construction

[0018] Embodiments of the present invention are further described below in conjunction with the accompanying drawings:

[0019] See Error! Reference source not found. , the high-speed imaging ultra-wideband ground-penetrating radar system of this embodiment is composed of an engineering vehicle 101 and a high-speed imaging ultra-wideband ground-penetrating radar system. The high-speed imaging ultra-wideband ground-penetrating radar system is a dual-band, dual-channel short-pulse radar. The signal and data processing unit and the display terminal 102 of the radar system are installed at the rear part of the engineering vehicle. At the rear of the car, there is an antenna installation box 104 for installing the radar antenna 103 . The radar transmitting antenna 501 and the receiving antenna 502 are installed at a height of 20cm-50cm from the ground. To avoid collision between the antenna and the ground during high-speed driving, both the transmitting antenna 501 and the recei...

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...
