Abstract
This paper describes a novel way to exploit the correlation-based (CB) imaging algorithm Excitelet, based on correlation of measured signals with reference signals. In this study, reference signals are approximated using an experimental baseline instead of computing it. The reference signals are obtained by experimentally measuring the Full-Matrix Capture (FMC) with individual reflectors located at one point at a time of a determined imaging grid. This experimental CB (Exp CB) approach makes fewer model assumptions than the numerical CB (Num CB) method, meaning that the baseline is closer to reality, resulting in better spatial resolution and contrast of the imaging.
