Ultra-Wideband sensing is basically a radar that transmits electromagnetic pulses and listens for reflected echoes in much the same way as a traditional radar does. We can sense all objects inside a defined coverage area, but we are particularly good at detecting objects that move, even if the movement is very small.
Here is how we do it
You can think of our radar as an air traffic control radar where everything has been miniaturized. And that means everything.
Size has been reduced from a tower with an antenna dome to a 12 mm by 12 mm module suitable for surface mount assembly on a PCB (printed circuit board). Cost is down by a similar factor. Power consumption is slated to pass below 1 mW total system power while actively scanning for approaching targets.
But there is a less obvious miniaturization that justifies the name Ultra-Wideband. The length of the transmitted pulse in an air traffic control radar can be several microseconds, meaning that it extends hundreds of meters in flight while travelling towards its target. Our transmit-pulses are around 1 ns long, spanning roughly 0.3 meters.
This enables us to detect and distinguish small objects in the size of human beings or even smaller animals. Combined with the ability to sense tiny movements of these objects, our technology is a perfect platform for the most reliable human presence sensors in the world.
