Doorway identification and classification using software-defined UWB OFDM radar

Abstract

This paper discusses the implementation of a set of functions that will allow a software-defined ultra-wideband (UWB) orthogonal frequency division multiplexing (OFDM) system to perform short-range indoor navigation. Specifically, we aim to illustrate the effectiveness of the software-defined radar system (SDRS) at identifying the presence of targets and doorways. Simulation results have been generated to demonstrate the levels of precision that are possible in identifying the location and width of doors from the enclosed indoor environment. These results are augmented with experimental results that form the back-end of an experimental implementation.
