Frequency-Diverse Computational Polarimetic Imaging

Résumé

In this paper, a frequency-diverse computational polarimetric imaging system is demonstrated at K-band (17.5-26.5 GHz) frequencies. The frequency-diverse operation enables all-electronic data-acquisition by means of a simple frequency-sweep and requires no mechanically moving apparatus or phase shifting circuits for imaging. Leveraging a tensor model for the scattering behavior, as opposed to a scalar model, enables the extraction of further information from the imaged objects. This is shown by means of frequency-diverse polarimetric imaging of complex objects, such as the letters of the word "DUKE", and comparing the reconstructed polarimetric images to the reflectivity-only reconstructions of the same objects. Index Terms-Imaging, antenna, metasurface, polarimetry, computational.
