The switches are used for interconnecting elements to form macro elements of the one-dimensional aperture on the multi-dimensional array. The switches are distributed on a grid corresponding to the desired imaging frequency. The acoustic elements are distributed with a finer pitch. The finer pitch allows formation of the macro elements for the one-dimensional aperture where the edges of the macro elements have fewer or no periodic patterns.01-27-2011
