Abstract
A method for generating a spatial distribution of acoustic transmitting frequencies by a time modulated array (TMA) of transducers includes generating, by a tapped delay line, a plurality of pulsed sampling signals, wherein each pulsed sampling signal includes a series of frequency harmonics and successive signals of the plurality of pulsed sampling signals are separated by a predetermined delay time; mixing each of the plurality of pulsed sampling signals with a time-limited information signal wherein a plurality of mixer output signals is generated; bandpass filtering each of the plurality of mixer output signals; generating a first plurality of simultaneous TMA beams from the plurality of filtered and weighted output signals by driving a plurality of acoustic transducers in a spatial array of acoustic transducers, wherein each beam of the first plurality of simultaneous beams is associated with one of a plurality of transmitting carrier frequencies
