Study of human being detection in an indoor environment using ultra wideband radar

This paper describes a method of human being detection that involves eigenvalue estimation and analysis. This is a tag-free live human body detection method that looks for small changes in the reflected Ultra Wideband (UWB) signals in an indoor environment. As chest movement of the human body leaves a distinguishable effect on the reflected UWB signal hence it is an observable and detectable phenomenon that has been targeted. This experimental study also incorporates detection of the target behind the wall.
