Abstract

Image sonar, also known as underwater camera, is widely used in engineering applications such as underwater target detection, imaging, and alert. It is an important naval military equipment. The directivity parameters of the transducer play a decisive role in the observation range and resolution of the image sonar. Improving the directivity of the image sonar transducer plays an important role in improving the quality of the sonar image. In this paper, a low-directivity undulating arc-shaped array is designed by using the elliptical long-axis array method, and the acoustic baffle is used to expand the directivity angle of a single element through the optimal design of boundary parameters. Simulation calculations and measured data show that the directivity fluctuation in the horizontal main beam range of the arc-shaped array is less than 3dB, and the horizontal directivity angle of each element of the receiving array is greater than 120°. The results show that the directivity characteristics of the image sonar transducer have been improved significantly.
