Low-Sidelobe Single-Sideband Time-Modulated Phased Array Using Stepped Waveforms With Different Amplitudes

Single-sideband time-modulated phased arrays (STMPAs) can suppress undesired sidebands and achieve convenient beam scanning without repeated time-consuming optimization, as compared to conventional time-modulated arrays (TMAs). However, most of STMPAs are limited to phase-only weighting arrays becau...
