In this paper, various positioning algorithms for range-based TOA and TDOA localization have been analyzed, which include the analytical method, least square method, approximate maximum likelihood method, Taylor series method, two-stage maximum likelihood method and genetic algorithm. The assumed scenario is an overdetermined system in a 3D space under line of sight (LOS) situation and a number of...
In this paper we give an overview on autonomous navigation, object detection and imaging by UWB sensor networks. We describe coherent and non-coherent approaches of data fusion for imaging and object localization that rely on different levels of synchronous multistatic and asynchronous sensor cooperation. Detection and identification of time variant object features are discussed.
