The avalanche radar is a C-band doppler radar designed for early detection of avalanches and landslides. It can detect the first movements during avalanche initiation and trigger alarms within 1.5 seconds, so that roads in the area can be closed immediately for the safety of the drivers.

​Advantages

  • Reliable monitoring of spontaneous and controlled triggered avalanches

  • Long range

  • Easy deployment

  • Autonomous operation in all weather conditions

  • Provides an estimate of the avalanche’s peak velocity and extension

Key features

  • Operational frequency: C-band (5.4 GHz)

  • Maximum range: 2 to 4 km

  • Early warning system with different levels of warning and alarms

  • Detections based on dedicated thresholds providing low false alarm rate

  • Output: Avalanche map in the range- Doppler domain, range and velocity profiles

The radar is part of Cautus Geo monitoring system, which uses the alarms generated by the radar to trigger light, sound, or dynamic signs on location, as well as send SMS and email alerts.

The alerts can be used to control the traffic on the roads which can be affected by the snow, thus protecting the drivers from potentially severe accidents.

Upon detection of a slide, an integrated optical camera starts recording.

 

All videos, as well as the radar measurements, such as velocity profiles and avalanche range doppler maps, are available on the web in near real time via the Cautus Web system.
