ABSTRACT:
An acoustic reflector is disclosed, which is formed from the surface generated by an ellipse rotated about 180.degree. about a line passing through one of the focal points of the ellipse, where this line of rotation intersects the major axis at an acute angle. A transducer placed at the focal point on the line of revolution will, when energized, generate waves that will be reflected from the surface back through the arc of second focal points of the generating ellipse.
