Abstract

This preliminary paper deals with the impact of the Time Reversal (TR) processing on the performance of an Ultra Wide Band (UWB) location system. In a first part, we describe the topology of the UWB location system we have developed. In a second part, we present the enhancement of UWB radio channel characteristics by applying a TR algorithm. We have considered an impulse response of the (UWB) radio channel corresponding to severe propagation conditions: TR signal processing is described and its benefits on the characteristics of the UWB Channel Impulse Response (CIR) are detailed. A third part presents first results on the reduction of the error location due to UWB multipath propagation.
