Two companies are demonstrating Ultra-Wide Band (UWB) radar systems providing through the wall sensing. Israel-based Camero is showing the Xaver 800 and 400 products and is unveiling a prototype design of the miniature hand-held Xaver 100, that fits into a soldier’s pouch. These systems can effectively detect the presence of people behind a wall, indicating their movements, relative positions and, in some systems, the distance to the target.

U.S. based TiaLinx Inc. has developed a different system, also utilizing a low-power UWB design. Actually, TiaLinx’ Eagle 5 family of radars can be used as ‘dual-use systems’ – for spotting and tracking targets behind walls, but due to its high sensitivity, the sensor can also detecting living people trapped under rubble, by spotting their breathing movements. The system can also detect underground cavities associated with weapon’s caches and IED emplacements inside walls.

The imager ‘illuminates’ the target area with rapid, wide-band high frequency (nano sec.)
pulses that penetrate glass, wood, concrete, dry wall and bricks. The pulses echoed from underground objects and ‘anomalies’ are processes to create a two-dimensional image of the target. The radar can detect objects buried 30 ft deep into the ground or covered by 20 cm concrete slabs.

TiaLinx offers two versions of the Eagle 5 – the Eagle 5P hand held RF imager for culvert and tunnel detection, and -5B model, designed for the detection of underground buried motion. Other models developed by the company are designed as hand held sensors, utilizing a helmet mounted display.

The Spanish company TechnoRobot has introduced here the RiotBot – a new class of unmanned platform designed for intervention in riots, prison disturbances, or other civil disorders, where neutralization of specific elements is required by law enforcement agents, avoiding direct contact with the crowd. By operating with effective non lethal means to suppress, or deactivate a target without the presence of personnel, RiotBot can eliminate potential threats while minimizing escalation typically caused by police intervention.

The Riotbot platform comprises a six-wheel electrically driven automotive system, fitted with rechargeable lithium batteries to last for two hours of continuous operation. Turnaround tasks include recharging the weapon’s compressed air tank, replacing batteries and reloading ammunition is performed in less than five minutes.

The riotbot weighs about 18 kg (40 pounds) and can travel at a speed of 20 km/h (12 mph), and its weapon are controlled from a game-style hand controller and portable console, monitoring and controlling the vehicle from a distance of one mile. The weapon mount employs a PepperBall TAC700 carbine customized and adapted for safe use on the robot. A video camera is attached to the mount, monitoring the weapon’s aiming line in its field of view. RiotBot packs 450 PAVA balls of ammunition feeding at 700 rounds per minute. The carbine is designed with safety measures enabling it firing only by remote control, therefore preventing hostiles from turning it against the operators.  The weapon can tilt at elevations of 30 degrees or depression of -15 degrees, and turn 150 degrees to each side. It is effective at distances from zero of 60 ft.

The system is operated by two persons, compared to four carrying a single patient on a stretcher. Furthermore, as the harness' load is carried on the shoulders, this leaves the carrier's hands free to assist in movement, treat the patient or use weapons for self defense.

Easy Rescue unveiled their latest innovation in casualty rescue and evacuation, introducing a new method to transfer wounded persons from areas under engagement or where movement or access are challenged by terrain, design (narrow paths), man made or natural obstacles. An operational study of such system conducted by the IDF Home Front Command indicated that such system can contribute to personnel saving by a factor of 5 – 10, compared to evacuation techniques employing only stretchers and gurneys.

The system developed by Easy Rescue employs a harness carrying a single patient in a seated position. Carried by two persons, the harness is recommended to evacuate people weighing up to 120 kg. The system is packed into a compact pouch weighing only 0.9 kg.
