[0025] specific implementation plan
[0026] The present invention will be further described below in conjunction with the accompanying drawings and a preferred specific embodiment of the present invention.
[0027] As a preferred embodiment of the present invention, the integrated multi-beam sounding device has an optional acoustic center operating frequency of 400 kHz, and the multi-channel receiving transducer array (115) is realized by a 96-element linear array structure. The spacing is 1.875mm, and each array element forms a receiving directional beam of 150° horizontally and 30° vertically, so that the natural directivity of the whole array is a uniform receiving line array of 1° horizontally and 30° vertically; the multi-channel transmitting transducer array (117 ) all adopt a linear array structure composed of 8-element U-shaped array elements, the array element spacing is 22.5mm, and each transmitting array element forms a transmitting directional beam of 150° horizon...
