Utilizing the energy of each of the extracted poles to identify the dominant complex natural resonances of the radar target

A novel technique, based on utilising the energies of the CNRs, has been introduced in this paper to identify the dominant poles, from a pool of extracted CNRs, of a simple PEC target in free space with different Signal-to-Noise ratios. The proposed dominant poles identification scheme does not require any knowledge of the modal order of the system. Applying this new technique to low Quality-Factor (Q-Factor) target and dielectric target will be the subject of further investigations.
