Classification of Electronic Devices Using a Frequency-Swept Harmonic Radar Approach

A new method to classify electronic devices using a Frequency-Swept Harmonic Radar (FSHR) approach is proposed in this paper. The FSHR enables us utilize the frequency diversity of harmonic responses circuits. Unlike previous studies, frequency-swept signal with constant power transmitted Electronic Circuits Under Test (ECUTs). response found be distinguishable for different types ECUTs. Statistical and Fourier features are derived classification. Later, characteristics ECUTs depicted 3D feature spaces Three-dimensional composed first three harmonics re-radiated statistical or features, respectively. We extensively evaluate performance our novel through Monte Carlo simulations presence noise.
