More Information
Summary:Phase information is used in many imaging modalities to enhance resolution, such as in magnetic resonance imaging. However, its impact in Ultra-wideband (UWB) microwave imaging is still unexplored. Here, examples using analytical simulations are shown to address the impact of phase information in Huygens principle (HP) based UWB imaging. Conventional amplitude-weighted HP imaging has a resolution, which achieves the optical resolution limit of λ/4, where A represents the wavelength in the investigation domain calculated at the highest frequency. Simulation results show that HP phase-weighted modality leads to an improvement in the resolution of approximately 30% with respect to the HP amplitude-weighted modality, and to an increase in signal-to-average ratio of approximately 40% with respect to the HP amplitude-weighted modality.
