Hexacopter Can Detect Motion and Breathing

Tweet

TiaLinx Inc. of California has debuted a long-standoff mini-UAV that acts as a motion detector and can detect the breathing of people in hiding. The Phoenix40-A unmanned aerial vehicle can be programmed to fly to or land at multiple waypoints and has been integrated with TiaLinx's fine beam ultra-wideband, multi-Gigahertz radio frequency sensor array.

The RF Scanner is mounted on a light weight mini-UAV and transmits wideband signals that are highly directional and can penetrate reinforced concrete wall at an extended range. In the receiver, a signal detector circuit is employed to capture the reflections from targets. Amplitude and delay information are processed in an integrated signal processor.

"Phoenix40-A's introduction is intended to provide another breakthrough in miniaturization of advanced life detection sensors that provide the capability to sense-through-the-wall remotely," said Fred Mohamadi, founder and chief executive officer of TiaLinx. "Like its sister product, Cougar20-H, that was launched last month, Phoenix40-A can also be remotely programmed to survey a compound at multiple waypoints. It can scan a multistory building and provide its layout. It is also capable of scanning on-road and off-road horizontally to detect buried unexploded ordnance." TiaLinx's real-time UWB RF Imaging development was sponsored by a SBIR Phase II from the U.S. Army.
