An apparatus for synthetic imaging of an object is disclosed. The apparatus includes a plurality of transmitter elements spaced apart by a first distance in a first column and a plurality of receiver elements spaced apart by a second distance in a second column. The first distance and the second distance are different. The plurality of transmitter elements is a non-integer multiple of the plurality of receiver elements, and the plurality of receiver elements is a non-integer multiple of the plurality of transmitter elements.
