A method for wideband transmit beamforming using integertime-delayed and phase-shifted waveforms is proposed. Unlike traditional true-time-delayed digital methods, which employ variable fractional delay filters or discrete Fourier transforms to create fractional time delays, the proposed method uses only integer-time-delayed waveforms with phase shifts corresponding to fractional time delays. Furthermore, the shifted phase can be directly generated; this generation can be simply achieved by controlling the parameters of a direct digital synthesiser. A beam pattern simulation confirms that the integer-time-delayed and phase-shifted waveforms are capable of synthesising wideband transmitting beam patterns. Finally, a power synthesis efficiency analysis demonstrates that the synthesis loss caused by phase shifting is negligible.
