Handheld Imaging Device for Security Applications

A standalone, handheld, through-wall radar unit is under development to provide three-dimensional feedback on the location and movement of people inside buildings. Applications include military and emergency service such as hostage situations and search and rescue. The unit, which can be held against a wall or mounted on a tripod located up to 2 meters away, transmits low-frequency ultrawideband (UWB) radar pulses that pass through building materials over 40 cm thick and detects activity over a range of up to 15 meters.
