Comparison of the time-reversal and SEABED imaging algorithms applied on ultra-wideband experimental SPR data

摘要

This paper presents a comparison study between a simple time-reversal algorithm (designed at LEAT) and the SEABED algorithm (designed at Kyoto University) with their application to multiple-target experiments. Data are collected with an eight element ultra-wideband antenna linear array connected to an eight port vector network analyzer, working in a frequency bandwidth starting from 1.5 GHz up to 8 GHz. Several target configurations demonstrate the advantages and disadvantages of both algorithms.
