The Trivue is a multi-frequency Ground Penetrating Radar (GPR) system comprising three bistatic bow tie antenna oriented around an identical common mid-point, and housed within a light weight rugged casing. The antenna also houses all electronics enabling data to be recorded to a rugged tablet or laptop running Windows OS (XP to 10) via wired or wireless network. An internal Li- Ion battery can run the system for up to 10 hours with the option of connecting an external battery for extended operation.
The high pulse repetition frequency coupled with unique stacking functions permit the three different frequency datasets to be recorded simultaneously without cross talk. The record length for each channel is independently selectable permitting the operator to have complete control over data acquisition.
The intuitive user interface and versatile display tools help an operator to quickly and easily analyse data in the field and implement quality control measures.
the wired network permits the antenna to be up to 250m from the laptop data recording device making the system ideal for use on quarry faces or earthen/concrete dams.
The 4 wheeled cart provides a robust stable platform for the antenna, allowing it to move freely over uneven ground surfaces. On very uneven ground the handle on the cart can be inverted to allow the system to be pulled behind the operator. Alternatively the TriVue can be fitted with a variety of trailing odometer wheels.
A built in GPS chip accurately time stamps each trace and provides simple positional information to aid corroborate field notes. An external survey grade GPS can be connected directly to the TriVue, jumping the internal GPS, for integrating accurate positioning. The GPS positions are received by the TriVue PCB to avoid any latency at high recording speeds. An optional Inertial Measurement Unit (IMU) can be fitted within the antenna to interpolated between GPS positions where dropouts are likely to cause positional difficulties. Heading can be used to record the line path where GPS positions are not available and itch and roll information permits advanced topographical corrections to be undertaken.
With a bandwidth of 125MHz-2GHz the Trivue is ideally suited for utility detection, ground engineering projects, environmental applications, and road and railway ballast assessment. The three antenna- 250MHz, 500MHz and 1GHz central frequency bowtie- mean the system analyses the subsurface in great detail and ensures an operator is equipped for all eventualities.
The system is ideal for many engineering and geotechnical studies, including; Utility detection, brownfield site mitigation, railway ballast assessment, road sub-base delineation.
TriVue data can be processed in a multitude of third party software packages including RelfewW, GPR SLICE, GPRSoft or RoadDoctor.
