Time-Modulated Multibeam Phased Arrays With Periodic Nyquist Pulses
(Institute of Electrical and Electronics Engineers, 2018-12)
[Abstract]: We present a single sideband time-modulated multibeam phased array governed by periodic Nyquist pulsed signals. A Nyquist pulse is a physically realizable approach to the ideal sinc function. Hence, its low-pass ...
Analog Beamforming Using Time-Modulated Arrays With Digitally Preprocessed Rectangular Sequences
(Institute of Electrical and Electronics Engineers, 2018-03)
[Abstract]: Conventional time-modulated arrays are based on the application of variable-width periodical rectangular pulses (easily implemented with radio frequency switches) to the individual antenna excitations. However, ...
