Abstract
A planar end-fire acoustic transducer array is composed of a planar matrix f individual elements. In order to give this array an end-fire characteristic, predetermined elements are provided with outputs which are phase-inverted with respect to the outputs of the other elements of the array, the sum of the gains of these predetermined elements being made equal to the sum of the gains of the other elements.
