System and method of acoustic doppler beamforming

摘要

A system and method for forming acoustic beams is disclosed. One embodiment is an acoustic system configured to generate a plurality of beams non-orthogonal to a transducer array simultaneously with a vertical acoustic beam orthogonal to the array. The acoustic system includes a plurality of transducer elements arranged to form a two-dimensional array and electrically connected into rows in a first dimension and columns in a second dimension.

1. An acoustic system, comprising:
a plurality of transducer elements arranged to form a two-dimensional array and electrically connected into rows in a first dimension and columns in a second dimension; at least two first beamforming circuits configured to generate a plurality of beams in at least two planes, each of the beams defining a non-orthogonal angle with the transducer array; and a second beamforming circuit electrically connected to each of the first beamforming circuits and configured to generate a beam orthogonal to the transducer array, wherein each of the first beamforming circuits is electrically connected to each of the transducer elements so that each of the transducer elements contributes to each of the beams in the at least two planes.
