摘要：
This paper studies a new techniques for localization system in railway transport using UWB radio and Time Reversal technique (TR) techniques. Communication and localization in rail applications represents a permanent and evolutionary need, motivated by the improvement of the quality and safety of transports. Ultra wide band appears as a very suitable technology for this kind of application, due to its large bandwidth, also to its good resistance to the interference and to multipath. Time Reversal channel pre-filtering facilitates signal detection and helps increasing the received energy in a targeted area. In this paper, we evaluate the characteristics of spatio-temporal focusing of time reversal on the one hand, and secondly we compare systems without time reversal UWB location and tracking systems with time reversal UWB in terms of error localization. These studies are conducted in simulation and experimentation.
