TiaLinx Inc., a developer of remotely controlled small unmanned aerial systems (sUAS) integrated with mm-wave miniaturized radars, announced launch of its software-defined multi-function radar sensor implemented in its vertical take-off and landing (VTOL) platform. The Phoenix50-A VTOL sUAS system is capable of performing various functions, such as motion detection within a compound, scanning the ground for unexploded ordnance (UXO), and non-line of site (NLOS) landing using fine beam ultra-wideband (UWB), multi-Gigahertz radio frequency (RF) sensor array. The sUAS can be remotely controlled at long standoff distances from the ground or an airborne asset. TiaLinx's real-time UWB RF Imaging development was sponsored by a SBIR Phase II from the Department of Army.
Through a software-controlled interface integrated with a laptop or joystick, Phoenix50-A can be remotely guided to perform mission critical tasks. In addition to the GPS based guidance system, the low acoustic signature sUAS can land on a desired premise using an undetectable radar. Upon landing, the RF sensor monitors the premise under surveillance for enhanced situational awareness.
The RF sensor transmits very low power UWB signal that is a fraction of a cellular phone's transmitter and is highly directional and can penetrate roofs at an extended range. At 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. Capability to probe a compound at standoff keeps the operator and the Phoenix50-A out of harm's way.
"Phoenix50-A's introduction is intended to provide another breakthrough in the miniaturization of advanced life detection sensors with the capability to sense-through-the-roof (STTR) remotely. Like its sister product Cougar10-B that was launched on February 2011, Phoenix50-A can also be remotely programmed to survey ground for UXOs. The additional feature of landing in NLOS has paved the road for delivery of autonomous platforms to be announced in the near future" 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 to enhance situational awareness, assist rescue operations in hard to reach terrains (such as collapsed buildings after an earthquake), and eradicate land mines to save lives."
