Abstract

A methodology for identification of multiple objects using their natural resonant frequencies is presented. This methodology is then applied to generate a library of poles of various objects in the frequency domain and compare them to the computed natural poles of unknown objects using the typical transient temporal late time response in thetime domain. TheCauchy method is applied directly in the frequency domain to extract the Singularity Expansion Method (SEM) poles, and thus a library of poles of various perfectly conducting objects (PEC) is generated. The Matrix Pencil (MP) method isthen applied tothelate time response to compute the SEM poles for identification in the time domain. Simulation examples are analyzed to illustrate the potential of this proposed methodology.
