Direct Antenna Frequency-Hopped M-FSK Modulation With Time-Modulated Arrays
(Institute of Electrical and Electronics Engineers, 2024-02)[Abstract]: We present an innovative approach that simultaneously enables direct antenna frequency-hopped M-ary frequency shift keying (DAFH-MFSK) modulation and beamsteering through the use of time-modulated arrays (TMAs). ... -
Time-Modulated Arrays Controlled With Sinusoidal Pulsewidth Modulation
(Institute of Electrical and Electronics Engineers, 2020)[Abstract]: In this letter, sinusoidal pulsewidth modulation (PWM) is applied to the design of time-modulated arrays (TMAs). The array excitations are modulated using PWM-synthesized sine waveforms. This provides increased ... -
Time-Modulated Arrays With Haar Wavelets
(Institute of Electrical and Electronics Engineers, 2020-11)[Abstract]. Time-modulated arrays (TMAs) can effectively perform beamsteering over the first positive harmonic pattern by applying progressively delayed versions of stair-step approximations of a sine waveform to the antenna ... -
TMA–FDA Range-Angle Beamforming With Periodic Linear-Phase Time-Modulating Waveforms
(Institute of Electrical and Electronics Engineers, 2022)[Abstract]: Frequency diverse arrays (FDAs) provide range-angle time-invariant transmit–receive beamforming, although a fine focus of their radiation patterns is costly since high-resolution mixers and phase shifters are ...
