ReTWis is a through-wall radar system capable of detecting, locating, and real-time tracking of living human targets concealed behind solid barriers. ReTWis is a truly portable device; it weighs 7 kg, including its battery, which provides sufficient power for an endurance of 9 hours. ReTWis can be used for a variety of different purposes and in as many ways; whenever you need to know whether there are living humans on the other side of the solid barrier and what their current location is.
ReTWis is an invaluable tool in every case where having visibility is essential. ReTWis can see through most common wall materials enabling its users to view living beings at a range of up to 20 meters. ReTWis is the tool which can help you to have a quick evaluation of room activity and it can also be used as a decision-maker tool.
The ReTWis through-wall radar is based on advanced Ultra-Wideband (UWB) technology utilizing short electromagnetic impulses to penetrate the wall. The signatures of targets hidden behind the wall are reconstructed by processing the reflected echoes from these targets. ReTWis is optimized for detecting small changes in the received electromagnetic energy induced by human motion; slight micro-movements caused by vital signs (e.g. respiration) are also captured and displayed on the screen. Ultra-low power electromagnetic emission transmitted by ReTWis (approx. 100× lower than the emission of a cellphone) is harmless for both the user and the people behind the wall.
Enhanced image processing implemented in ReTWis enables the user to determine the position of the targets, observe their movements in real time, distinguish between moving and stationary (just breathing) targets, and recognize their activity. In most application scenarios, ReTWis is assumed to be placed close to the wall. However, it is capable of operating in standoff mode as well (mounted on a tripod). In general, ReTWis can penetrate through wall materials that are transparent for radiowaves, e.g., drywall, wood, concrete, adobe, and brick. A unique feature of the ReTWis system is its capability of seeing through perforated brick-walls. The extreme thickness and high moisture content in the wall material may negatively impact the maximum radar range. Obviously, ReTWis can't see through continuous metallic sheets.
Application of ReTWis by military, police and special forces protects lives of soldiers in unknown urban environments as well as lives of hostages during counter-terrorist operations. ReTWis is also a highly versatile tool for rescue teams, especially in the case of fire and natural disasters.
