RIS Hi-BrigHT: Applications

All rights reserved to IDS 2 May 2013

IDS RIS Hi-BrigHT The only specific radar solution for bridge deck analysis

• RIS Hi-BrigHT introduces a new approach in bridge inspection by GPR technology, thanks to:

• The 16 channels antenna array at 2 GHz for high resolution 3D Tomography which allows a better data interpretation.

• The antenna array with double polarization (8 antennas in VV polarization and 8 antennas in HH polarization) to provide detailed information on defects.

• The GRED HD 3D Bridge software, a dedicated tool for bridge analysis

• The lightweight and compact design which allows high maneuverability, fast and easy data collection.

Benefit from double polarization

HH channels

VV channels

Double polarization, 8 antennas VV + 8 antennas HH, provides detailed information on defects • Hyperbolas produced by shallower rebars can be better detected in HH data • Hyperbolas produced by deeper objects/rebars can be better detected in VV data

Market and possible customer The market is really interesting and not difficult to address. Can be divided in three major objectives:

• Service provider for bridge condition assessment. Typically those company are really few and can be contact directly.

• Geophysical Survey Company.

• Local Road and Bridge Agencies/Authorities. Based on the country you can investigate how to meet the person in charge of those survey.

• University and Research Center: Civil Engineering Department

• Company Managing the Highway Network (including bridges)
