Field repeatability in frequency diverse imaging


Conference Paper

© 2016 IEEE. We consider multi-static imaging systems composed of frequency-diverse transmitting antenna arrays (or apertures). In these frequency diverse imaging modalities, accurate near-field characterization of the antennas is vital to achieving imaging. It is shown that considerable simplification in system characterization can be achieved without compromising the image quality when planar cavity antennas are used, because their radiation characteristics can be manufacture repeatable. In contrast, it is also demonstrated that the increased complexity of antennas utilizing sub-wavelength elements significantly reduces fabrication tolerances, making it necessary to characterize the metamaterial apertures individually.
