Problems solved by technology

[0002] The existing underwater acoustic measuring instruments in China can be divided into two categories: noise measuring instruments and echo measuring instruments, both of which belong to the proprietary measuring frequency band, which cannot be reused in terms of hardware and software resources, which brings waste of cost to users. At the same time, the special use of measurement frequency bands and the dispersion of functions have brought inconvenience to users.

Abstract

The invention discloses a common underwater acoustic measurement system mainly composed of a transmitting transducer set, a transmitting extension set, a receiving extension set and a display control extension set. The display control extension set is connected with the transmitting extension set and the receiving extension set. The transmitting extension set is connected with the transmitting transducer set and used for driving the transmitting transducer set. The transmitting transducer set is used for finishing underwater launching of acoustic signals in a working frequency band. The transmitting extension set is used for finishing generation of underwater acoustic measurement signals and driving the transmitting transducer set, the receiving extension set is used for finishing receiving, conditioning, collecting and storing of the underground acoustic signals, and the display control extension set is used for finishing parameter setting, transmitting and receiving controlling, state monitoring, received waveform displaying and target strength calculating. The common underwater acoustic measurement system is high in universality and performance cost ratio and convenient to carry and use, the modular design is adopted, and subsystems can be independently used.

Description

technical field [0001] The invention relates to the technical field of acoustics, in particular to a general measurement system for underwater acoustics. Background technique [0002] The existing underwater acoustic measuring instruments in China can be divided into two categories: noise measuring instruments and echo measuring instruments, both of which belong to the exclusive measuring frequency band, and cannot be reused in terms of hardware and software resources, which brings waste of cost to users. At the same time, the special use of measurement frequency bands and the dispersion of functions have brought inconvenience to users. Contents of the invention [0003] Aiming at the technical problems in the above-mentioned prior art, the present invention provides a general underwater acoustic measurement system for measuring the target strength of an underwater target to be measured and capable of function expansion. The universal underwater acoustic measurement syste...
