- W2024690250 abstract "An improved split-beam transducer for a 50 kHz fish-sizing echo sounder was developed. The main objective of this study was to minimize the side lobe level in the beam pattern and the distance between acoustic centers for adjacent transducer quadrants in the geometrical arrangement of array elements while maintaining a given number of transducer elements and beam width. To achieve these goals, a 32-element planar array transducer (<TEX>$6{times}6$</TEX> array with one element in each corner missing) was designed using the Dolph-Chebyshev shading function to suppress side lobes in the array beam pattern and fabricated by arranging the inter-element spacing to be substantially equal to half the wavelength using the transducer element of 0.4 times the wavelength in diameter. The performance characteristics of this split-beam transducer were evaluated in the experimental water tank of <TEX>$5m{times}5m{times}6m$</TEX> (length<TEX>${times}$</TEX>height<TEX>${times}$</TEX>width). In this study, the design goal of the beam width and side lobe level for transmitting a beam pattern was initially set at <TEX>$21^{circ}$</TEX> and -30 dB, respectively. However, the measured beam width at 3 dB was <TEX>$21^{circ}$</TEX> in both directions with side lobe levels of -24.7 dB in the horizontal plane and -25.6 dB in the vertical plane. The averaged beam width at -3 dB of the receiving beam patterns for four receiving quadrants was <TEX>$31.4^{circ}$</TEX>. The transmitting voltage response was 161.5 dB (re <TEX>$1{mu}Pa$</TEX>/V at 1 m) at 50.23 kHz with a bandwidth of 2.16 kHz, and the averaged receiving sensitivity for four receiving quadrants was -178.13 dB (re 1 V/<TEX>${mu}Pa$</TEX>) at 49.8 kHz with a bandwidth of 2.64 kHz." @default.
