HYDRA ArcSAR: Applications of a portable InSAR system for monitoring geo-constructions

Research output: Contribution to conferencePoster


GBInSAR (Groung-Based Interferometric Synthetic Aperture Radar) is a robust, real-time and continuous monitoring method that is well suited for assessing geotechnical deformation processes and infrastructure health. Measurements are made remotely, are largely independent of light and weather conditions, and the intrinsic displacement resolution is in the sub-millimeter range. One of the drawbacks of traditional GB-InSAR equipment relates to its large size, heavy weight, and significant on-site infrastructure requirements. These drawbacks have recently been addressed through the development of portable ArcSAR technology, which is similar to traditional GB-InSAR; the main difference being that the antenna aperture is synthesized through radial rather than linear movement during data acquisition.

The first ArcSAR measurements in Austria have recently been conducted at the Zentrum am Berg tunnel research facility located at the Erzberg mine in Styria. Using the HYDRA ArcSAR system developed by IDS GeoRadar, the initial tests have included portal development (turn-under), monitoring of the tunnel face and breakthrough intersections, and lateral deformations of earthen embankments.
