Direct sampling method for imaging small anomalies: real-data experiments
arXiv:1803.05309 · doi:10.1016/j.aml.2019.04.016
Abstract
A direct sampling method (DSM) is designed herein for a real-time detection of small anomalies from scattering parameters measured by a small number of dipole antennas. Applicability of the DSM is theoretically demonstrated by proving that its indicator function can be represented in terms of an infinite series of Bessel functions of integer order and the antenna locations. Experiments using real-data then demonstrate both the effectiveness and limitations of this method.
