Abstract

The invention provides a signal leading-out method and system of a multi-channel high-frequency receiving transducer array. The method comprises the steps of S1, acquiring signal output channel numberinformation of the multi-channel high-frequency receiving transducer array and signal output mode information of the multi-channel high-frequency receiving transducer array; S2, constructing a front-end circuit board of a receiving system; S3, setting a distance from a transducer array element to the front-end circuit board; S4, constructing an FPC flexible circuit board; S5, correspondingly welding or inserting one end of the FPC flexible circuit board into the front-end circuit board; S6, welding a section of wire on each element of the transducer array; S7, correspondingly welding each wire to the other end of the FPC flexible circuit board; S8, adhering copper foil adhesive tapes to the two surfaces of the FPC flexible circuit board; S9, fixing the two ends, close to the welding points, of the FPC flexible circuit board; and S10, detecting an insulating property; The method and the system are reasonable in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of underwater acoustic engineering, in particular to a signal extraction method and system of a multi-channel high-frequency receiving transducer array. Background technique [0002] High-frequency sonar has become one of the most important marine survey and survey instruments in domestic and foreign marine scientific research, seabed resource development, marine engineering construction and other marine activities. As an important part of the underwater wet end of the receiving system, the multi-channel high-frequency receiving transducer array performs narrow-beam reception on the echoes of the seabed or targets, and obtains relevant information of the seabed or targets by processing the received signals. Multi-channel high-frequency receiving transducer arrays generally require very sharp beam directivity in order to achieve high resolution of fine targets. [0003] High-frequency receiving transducer ar...
