PETRA® People Tracking Radar

To monitor endangered areas in order to make sure no people are exposed to controlled released avalanches if visibility is poor

Functional principle

The Doppler radar sends out electromagnetic waves, which are reflected by objects. The reflected radiation from moving objects has a different frequency than the transmitted radiation (Doppler effect), which is used to detect and track people. The data is sent to a server for processing and visualizing.
