Embodiment Construction
[0043] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0044] Such as figure 1 As shown, when using a related velocity measurement sonar system to measure the flow layer velocity of a fluid medium, the system is loaded on a carrier 100. The related velocity measurement sonar system generally includes a sonar array 200, a wet end 300, a dry end 400, and a terminal 500. . Among them, the sonar array 200 and the wet end 300 are installed under water, and the dry end 400 and the terminal 500 are installed on the water surface.
[0045] The structure of the related speed sonar system is as figure 2 As shown, it includes a sonar array 200 and an electronic extension; the sonar array 200 includes a receiving transducer 203, a transmitting transducer 202, and a transceiver transducer 201, which are composed of the receiving transducer 203 and the transceiver transducer 201 The receiving sonar array is composed o...
