The Design And Realization Of Sonar Releaser Hardware Circuitry

Underwater acoustic releaser has been used widely as an essential laboratory equipment along with the development of China's scientific research and marine engineering applications. Underwater acoustic releaser is used in the marine monitoring, and inmarine engineering, all kinds of base-type ocean parameters measurement system and underwater acoustic targets need release device. So it is necessary to develop underwater acoustic releaser of our country.The paper introduce the development of underwater acoustic releaser in the world, the main work of the paper is listed: design all the parts of the hardware as the design parameters of the project, make the low noise analog reciever, high power underwater acousitc signal transmitter, low power watch circuit, DSP digital signal processing board and power management circuit.After experiment, the results confirm that the receiver and transmitter of underwater acoustic releaser and DSP digital signal processing board all met the parameters expected of the project.
