Re: Phoenix UAV can sense you breathing

Does my breathing produce rf signals?

your body interacts with them: "... a fine beam ultra-wideband (UWB), multi-Gigahertz radio frequency (RF) sensor array ... mounted on the robots lightweight arm transmits highly directional wideband signals that are able to penetrate reinforced concrete walls at an extended range. Reflections from the targets are captured by a signal detector circuit in the receiver and amplitude and delay information is then processed in an integrated signal processor to track the targets in real time."
