Abstract
A method and apparatus are disclosed for selectively reinforcing an acoustic wave traveling in a first predetermined direction in a body of water while attenuating an acoustic wave traveling in a second opposite direction. The output signals from vertically spaced receivers are appropriately delayed and summed to reinforce a wave traveling in the first direction and attenuate the wave traveling in the opposite direction. The invention is particularly useful for reinforcing desirably detected ascending acoustic waves and attenuating undesirably detected surface reflected descending waves.
