Human Body Detection using UWB-IR Indoor Channel

Delay profile of an indoor ultra-wideband impulse-radio (UWB-IR) channel should change for the movement of a human body. This paper suggests a human body sensor using the UWB-IR in order to protect a house, not a room, because the radio with high range resolution can penetrate into the walls and the reflected paths from human body and the like should be able to be discriminated in time domain. The usefulness is experimentally investigated under a scenario which a human intrudes into a typical house with four rooms and walks around. It is found from the results that the intruder should be recognized everywhere he stands in the house.
