Abstract
A digital multiline beamformer is provided which produces multiple receive beams in response to a single transmit event. An embodiment of the present invention includes a bulk delay which provides a common steering delay applicable to all of the beams received at one time. The bulk delay is succeeded by parallel filter processing paths which produce finely focused multiple beams simultaneously. In one embodiment a multiphase filter produces the samples for multiple beams, which is advantageous when the number of simultaneously produced beams is greater than the number of phases produced by the fine focus filter.
