Mini-UAV Detects Motion, Breathing Behind Walls

By on Wednesday, March 23rd, 2011

TiaLinx, Inc., a developer of remotely controlled mini-unmanned aerial and ground vehicles integrated with mm-wave miniaturized radars, today announced the launch of the Phoenix40-A.

The mini-UAV system is capable of performing dual functions as a motion detector as well as probing for breathing of a hiding person in a compound. The mini-UAV can be remotely controlled at long standoff distances from ground or an airborne asset.

The lightweight and agile mini-UAV with programmability to fly to or land at multiple waypoints has been integrated with TiaLinx’s fine beam ultra-wideband (UWB), multi-Gigahertz radio frequency (RF) sensor array. The system provides long standoff surveillance of a premise to track movement as well as to detect motionless live objects.

TiaLinx’s real-time UWB RF Imaging development was sponsored by a SBIR Phase II from the Army’s PEO AMMO, PM-CCS.

Through a software-controlled interface which is integrated into a laptop or joystick controller unit, Phoenix40-A can be remotely guided from long distances to perform mission critical tasks. In addition to the programmed GPS guided multi-waypoint visits, the integrated video cameras allow for day and night landing and monitoring of a premise under surveillance for enhanced situational awareness. Capability to probe a compound at standoff keeps the operator and the Phoenix40-A out of harm’s way.

The RF Scanner is mounted on a lightweight 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 then 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 (STTW) remotely. Like its sister product Cougar20-H that was launched last month, Phoenix40-A can also be remotely programmed to survey a compound at multiple way points. It can scan a multi-story building and provide its layout. It is also capable of scanning in-road and off-road horizontally to detect buried unexploded ordnance (UXO),” commented Dr. Fred Mohamadi, Founder and CEO of TiaLinx.

“TiaLinx is constantly miniaturizing and upscaling its UWB RF imaging core competence to enable standoff sensing of a premise for enhanced situational awareness, to assist rescue operations in hard-to-reach terrains such as collapsed buildings after an earthquake, and to eradicate land mines to save lives.”

TiaLinx, Inc. is a privately held company that develops advanced electronic modules with very small form factor, highly integrated functionality and advanced performance for wide range of military and commercial applications. Since 2006, TiaLinx has received 7 Phase II and CPP awards from various government agencies.
