Abstract
Time-Modulated Arrays (TMAs) perform angular diversity through the adaptive beamforming of their harmonic patterns with the advantage of employing a single Radio Frequency (RF) front-end. Rectangular pulses typically used in TMAs are not the best ones to efficiently distribute the spectral energy among the harmonics exploited. We propose a family of pulses, the so-called Sum of Weighted Cosines (SWC), which despite its simple form, allows for a flexible windowing of the harmonics involved while opening the door to a multimode TMA.
