Time-Reversal Based Range Extension Technique for Ultra-Wideband (UWB) Sensors and Applications in Tactical Communications and Networking

Abstract

This technical report (quarterly) details the work for Office of Naval Research (ONR) by Tennessee Tech. The goal of this project - jointly funded by ONR, NSF, and ARO - is to build a general purpose testbed with time reversal capability at the transmitter side. The envisioned application is for UWB sensors and tactical communications in RF harsh environments where multipath is rich and can be exploited through the use of time reversal. The report summarizes the results for each of three major tasks. The central task of this project is to address unique (rich) multipath problems faced with system design and implementation. The 1G testbed is working over the air and almost finished - except for an issue related to the high-speed interface between the FPGA and A/D converter. Currently, the 2G testbed is ongoing and very unstable - we are integrating the transmitter system in our Lab. More details are expected to be reported in the next report.
