ABSTRACT:
A capacitor goniometer type tilt compensator is provided for the bi-directional elements in a transducer array in which each pair of bi-directional transducers is tilt or twist compensated to make image lobe cancellation possible. This is done by a specialized capacitor goniometer type compensator at each pair of bi-directional transducers which modifies their outputs in accordance with the deflection angle from the local vertical so as to obtain an output signal substantially the same as would be obtained by a single, properly oriented bi-directional transducer.
