IDS North America Logo
IDS North America
Equipment Manufacturing Company  |  Corporate Member

IDS GeoRadar is a world leader in designing and providing products for subsurface investigations, monitoring of structural, slope and geohazard ground movements and vibrations. IDS GeoRadar provides instruments in theGround Penetrating Radar (GPR) and Interferometric Radar (InSAR) product sectors.

The IDS solutions for GPR are developed for near surface high-resolution subsurface investigations of the earth. Ground Penetrating Radar uses radio wave reflections (frequency from 25 MHz to 3,000 MHz) to collect information of underground or within a structure such as buried pipes, underground cavities, subsurface cracks, voids and layer thicknesses. IDS evolved the concept of standard ground penetrating radar introducing the concept of multi-frequency, multi-channel ground penetrating systems. IDS GPR products include: Aladdin, Opera Duo, RIS Hi-BrigHT, RIS Hi-Pave, RIS MF Hi-Mod, RIS One & RIS Plus, SRS SafeRailSystem, Stream EM, Stream X.The IDS IBIS family of radar interferometers that monitor structure movements and vibrations (bridges, buildings, dams, historical monuments, towers etc.) and ground movements (mine walls, Geohazards, glaciers, land subsidence) are an increasingly important set of tools for today’s construction, geotechnical, and transportation engineers. IDS Interferometric radar solutions, embodied by the IBIS range of products, provide innovative and unique solutions for remote, long range, continuous real-time inspection of the above mentioned areas, spanning from structures to geological environments, by measuring the phase difference of reflected waves to provide a detailed image of all displacements. IDS Interferometric radar products include: IBIS-FS, IBIS-FL, IBIS-FM, IBIS-Rover, IBIS-FMT, FPM360.
