Abstract
Positioning acoustic receivers to sense an incoming acoustic wave uses a first receiver adjacent to a second receiver. The first and second receivers have a center point along a first axis. A third receiver is adjacent to the first receiver. A center point of the third receiver is along a second axis perpendicular to the first axis. A third axis, perpendicular to the second axis, crosses the center point of the third receiver. A fourth axis crosses the center point of the second receiver and is perpendicular to the third axis. A fourth receiver is adjacent to the second and third receivers. A center point of the fourth receiver is an offset distance from the third and fourth axes. The offset is greater than zero but less than one-half a wavelength of an incoming acoustic wave.

A method for positioning acoustic receivers for sensing an incoming acoustic wave, comprising:
- providing a first acoustic receiver having a center point;
- positioning a second acoustic receiver adjacent to the first acoustic receiver, wherein the second acoustic receiver has a center point, wherein the center points of each of the first acoustic receiver and the second acoustic receiver are positioned along a first axis;
- positioning a third acoustic receiver adjacent to the first acoustic receiver, wherein the third acoustic receiver has a center point, wherein the center points of each of the first acoustic receiver and third acoustic receiver are positioned along a second axis, wherein the second axis is perpendicular to the first axis, and wherein a third axis crosses the center point of the third acoustic receiver and a fourth axis crosses the center point of the second acoustic receiver, wherein the third and fourth axes are different from the first and second axes, respectively, and are perpendicular;
- positioning a fourth acoustic receiver adjacent to the second acoustic receiver and the third acoustic receiver, wherein a center point of the fourth acoustic receiver is positioned an offset distance from each of the third axis and the fourth axis;
- and
