摘要:
The effect of ring scatterers on the directivity pattern of a small sonar transducer at an air‐water surface was studied. The rings were made of styrofoam and brass. The soft (styrofoam) ring narrows the pattern significantly whereas the hard (brass) ring seems to have much less effect. This pattern narrowing may make the ring a useful device in reducing the acoustic interaction between sonar array elements.
