摘要:
A method to shape a transmit beam pattern of a transmitter array. A basel time delay/phase coefficient is set for each transmitter. A plurality of beam pattern intensities are iteratively generated using the set of baseline time delays/phase coefficients and a plurality of sets of adjusted time delays/phase coefficients. Each beam pattern intensity has a unique set of time delays/phase coefficients associated therewith. Each one of the sets of adjusted time delays/phase coefficients differs from the set of baseline time delays/phase coefficients by only one time delay/phase coefficient. Each beam pattern intensity is compared with the optimal beam pattern intensity to determine which one of the set of unique time delays/phase coefficients minimizes a difference between the optimal beam pattern intensity and a corresponding one of the plurality of beam pattern intensities. The set of baseline time delays/phase coefficients is then replaced with the one of the set of unique time delays/phase coefficients that minimizes the difference. The above steps of iterative generation, comparing and replacing are repeated until the difference can no longer be reduced.
