When the acoustic vector sensor is installed on underwater carrier to detect and position targets, the measuring results will be influenced by the diffraction of the carrier. Due to the differences of the sizes and shapes of the carrier, the influences of the diffraction on acoustic vector sensor are also different. Using BEM, the influences of cylinder’s size and shape of undersurface on the directivity of acoustic vector sensor are calculated in this study. The results show that: the influences of diffraction on acoustic vector sensor are proportional to the length of cylinder’s radius and height; besides, the sharper the undersurface is, the less influences acoustic vector sensor subjects to diffraction of the carrier. The experiment that carried out in the lake proves the validity of the computing. The research is effective guidance for the application of acoustic vector sensor.
Key words: Acoustic vector sensor, cylindrical carrier, directivity, size and shape of undersurface, , ,
