Tornado Detector

For low altitude tornados

The Tornado Detector, currently available in prototype formats, uses a low power Doppler radar to sense tornadoes up to two miles away, day or night.

Once detection is made, data on the tornado is sent via a dedicated wireless link to a central location.  From there, warnings to other receivers and alarm devices may be made.  

Warning time is nominally 5 minutes, depending on the tornado’s approach speed.  

The unit is available with either solar power or 110 V ac powered.  The solar system has a battery back up, thus does not depend on electricity from the power company which often fails during storms.

Mounted on top of a 16’ to 35’ mast, the Tornado Detector constantly sweeps the horizon, with its sensor aimed just above the tree line, scanning for tornadoes that are on or near the ground.  It may be used in rural areas and small communities as an individual unit, or in urban areas as part of a network where units are spaced at 1 mile intervals for protecting city wide areas. 

Electronic filtering inside each unit suppresses false alarms from aircraft and blowing rain, snow or leaves.
The radar detector may be turned ON or OFF via the peer-to-peer data link.
