based on a technology which uses radio waves of the UWB (ultra
wide band) radar system and can reproduce three dimensional
images of movements behind a wall, up to twenty meters far
away. The reproduced
images are similar to those obtained by ultrasound scans, with a quite precise resolution.
This invention can be applied not
only to military purposes,
saving lives of soldiers engaged in anti-terrorism actions
in urban environment, but also in the
battle against crime, for instance in the search of kidnapped
people, and for civil purposes, in the search for survivors
after a natural disaster.
When it comes to saving people in a collapsed or burning
building the time factor is essential. Often the rescue
squads have to spend plenty time and energy to move the
debris, or risk their lives among fire without being sure
whether there are lives to save behind the walls.
