UWB Radar Based Localization of a Person Changing the Nature of Their Motion State

In the last decade, it has been shown that short-range ultra-wide band radars can provide the efficient solution to tag-free person localization for line-of-sight and non-line-of-sight scenarios. To localize people correctly using this technology, the corresponding detection methods have to be selected according to the nature of person motion state. On the other hand, people monitored in the case of real-life scenarios are moving by different styles, which are usually changing. It results in the need to develop complex radar signal processing methods allowing to detect and localize people moving with changing the nature of their motion state. Motivated by this finding, we will deal with the problem of person localization for such scenarios in this paper. Firstly, we will introduce a helpful classification of persons according to the character of their motion states. Then, using this classification and already known radar signal processing procedures for moving and static person localization, we will develop a novel concept of radar signal processing procedure for UWB localization of a person changing the nature of their motion state. A finally, good features of this concept will be demonstrated by its application for through-the-wall localization of a single person moving with a short and long stops.
