Taylor Series Based Localization Method of Moving Persons in 3D Space by UWB Sensors

During the last decade, great attention has been devoted to person localization by ultra-wideband (UWB) sensors. Whereas the issue of person localization in 2-dimensional space (2D) has been discussed in many papers, only a few papers have been devoted to people localization in 3D. In order to fill this gap, a new approach to the person localization in 3D will be introduced in this article. The proposed localization method referred to as the Taylor series based localization method (TSM) is based on the application of the well-known principle of the Taylor series method in combination with the 3D-2D method or its modification. The performance properties of the TSM method will be illustrated by its performance for an experimental indoor scenario intent on through-the-wall localization and tracking of a moving person by a multistatic UWB radar system.
