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. In the past three months our focus has been on improving the transmitter baseband and making use of full functions of the D/A. Our next work items include improvement of the time acquisition to support transmission over longer distance. We are designing a new synchronization head, and will implement and test the function on the FPGA based platform. We will soon have a improved version of time reversal system over the air, and some field tests at extended range are expected in early 2009. For technology transfer, the evolution of this testbed toward a multi-GHz wideband cognitive radio is promising.
