中文摘要:
      文章介绍了一种二阶镶拼圆管矢量接收换能器的设计方法,获得了类偶极子指向性以及波束宽度更为锐化的类四极子指向性。利用理论计算以及有限元仿真分析了镶拼圆管的指向性以及接收灵敏度,并实际制作了二阶镶拼圆管矢量接收换能器。在消声水池的测试表明,灵敏度测试结果与有限元仿真计算结果吻合较好,镶拼圆管矢量接收换能器类偶极子指向性图-3 dB波束宽度在95°左右,类四极子指向性图-3 dB波束宽度在40°左右,二阶矢量指向性图波束宽度明显比一阶矢量指向性图波束宽度更加锐化。
英文摘要:
      A design method for the second order vector receiving transducer composed of a segmented ring is introduced in this paper, which has both the quasi-dipole directivity pattern and the quasi-quadrupole directivity pattern with sharper beam width. The directivity and sensitivity of the segmented ring is analyzed by theoretical calculation and finite element simulation, and the second order vector receiving transducer based on the segmented ring is developed. The tests in an anechoic tank show that the measured sensitivity is in good agreement with the finite element simulation results. The -3 dB beam-widths of the quasi-dipole directivity pattern and the quasi-quadrupole directivity pattern are about 95° and 40° respectively. The beam width of the second order vector directivity pattern is sharper than that of the first order vector directivity pattern.
