HYDRA-G is a compact, remote sensing monitoring system designed for early warning and real-time measurements of sub-millimetric displacements in buildings, dams, tunnels, mining infrastructures, and cut-slopes.

HYDRA-G is able to provide real-time monitoring of civil structures and cut-slopes deformations and trigger early-warning alerts in case of impending collapses to evacuate people and machinery at-risk.

With a scan range up to 800 metres, the system provides the high-accuracy and resolution radar technology. HYDRA-G exploits the cutting-edge ArcSAR technology, providing a spatial resolution of centimetres with updated displacement information every 30 seconds.

An optical and infrared HD camera provides real-time visual inspection of monitored areas, and radar data are draped on a 3D model of the scene created by the built-in laser. The industry-leading HYDRA Guardian software provides an easy-to-use and powerful tool to visualize and interpret radar data, and perform analysis of displacement trends of structure and cut-slope movements. Moreover, SurfScan is a dedicated, real time building displacement and deformation analysis software.


  • Non-intrusive technology: no pointers or devices to be installed on the target

  • Hyper spatial resolution: to detect even the smallest displacement with sub-millimetric displacement accuracy

  • Fast acquisition rate: 30 seconds for a full resolution scan

  • Short range and large angular coverage capability: to track in real-time thousands of points in the monitored scenario

  • On-site results: data provided in real time with instant processing

  • 3D representation and visual imaging: to ease data interpretation of the monitored area

  • Compact and portable solution: easily transportable from a location to another and installed by one single person

  • High availability with low maintenance costs: minimal moving parts and low profile design to guarantee robustness and maximum availability in harsh environmental conditions.

Triple S: Slope. Structure. Safety.

In this episode of HxGN TV 2018, we discuss how interferometric radar is used in an academic setting.
