The problem of threshold performance improvement of direction finding using estimator bank approach is considered. The modified unitary Root-MUSIC estimator and pseudo-noise resampling are used to form the estimator bank. The classification of roots of the modified unitary Root-MUSIC polynomial based on their proximity to the unit circle is used on the final step of proposed approach.
The results of analysis of the photonic beamformer for an ultrawideband receiving antenna array are presented. The beamforming scheme is based on a “true-time-delay” method and optical fiber chromatic dispersion, and completed of components available on the market of fiber-optic analog communication systems implementing the Dense Wavelength Division Multiplexing (DWDM) technology. The technique is...
Development of the theory and technology of the small element antenna arrays is one of the research areas of the Department of Technical Electromagnetics and Radio communication Systems since 2006. The research is focused on the improvement of the mobile communication systems. Curvilinear antenna arrays are proposed that comprise antenna elements with controllable polarization of radiation, which...
