- Title
Hardware Suitability of Complex Natural Resonances Extraction Algorithms in Backscattered Radar Signals.
- Authors

- Abstract
Complex natural resonances (CNRs) extraction methods such as matrix pencil method (MPM), Cauchy, vector-fitting Cauchy method (VCM), or Prony's method decompose a signal in terms of frequency components and damping factors based on Baum's singularity expansion method (SEM) either in the time or frequency domain. The validation of these CNRs is accomplished through a reconstruction of the signal based on these complex poles and residues and a comparison with the input signal. Here, we perform quantitative performance metrics in order to have an evaluation of each method's hardware suitability factor before selecting a hardware platform using benchmark signals, simulations of backscattering scenarios, and experiments.
