A TDOA localization method based on de-embedding the propagation background

Abstract

A novel source localization algorithm that combines the time difference of arrival (TDOA) method and a technique for the de-embedding of the propagation transfer function for non-line-of-sight (NLOS) propagation is proposed, in order to achieve accurate source localization under NLOS conditions. An iterative implementation of the method is given, and results are shown for a simple case of a single wall obstacle.
