Real-time noncoherent UWB positioning radar with millimeter range accuracy in a 3D indoor environment

Abstract

In this work, we have successfully developed a stand-alone system for positioning both static and dynamic targets in an indoor environment with approximately 2 mm and 6 mm of 3-D accuracy, respectively. The results are considered a great milestone in developing such technology. 1D and 3D experiments have been carried out and validated using an optical reference system which provides better than 0.3 mm 3D accuracy. Such a high accuracy wireless localization system should have a great impact on many applications that require such high positioning precision.
