is previewing the second generation of its through-wall radar technology. Providing 3D feedback on the location and movement of people inside buildings, the system is being reengineered as a standalone handheld unit.

In this new version of the radar, Prism 200, Cambridge Consultants reportedly eliminate the need for an external controller and man-machine interface. This is achieved by integrating a VideoCore processor, which combines high-performance digital signal processing capabilities with a display driver. Results are presented instantly on the unit's built-in 6.4-inch colour display or, alternatively, transmitted to a remote laptop.

Building on the first-generation Prism 100 radar, the new radar will offer features that will enhance the efficiency and safety of military and emergency service personnel in situations such as hostage taking, search and rescue.

Held against a wall or mounted on a tripod up to two metres away, Prism 200 transmits low frequency ultra-wideband (UWB) radar pulses that pass through building materials over 40 cm thick, to detect activity over a range of up to 15 metres.
