The Design of Underwater Acoustic Broadband Amplifier Signal Generator and Controller Based on Virtual Instrument

In view of underwater acoustic complex broadband signal and power amplification matching difficulties of problem, there presenting underwater acoustic broadband power amplifier and matching system generator methods based on virtual instrument technology, and designed the multifunction underwater acoustic broadband amplifier signal generator and controller system for underwater sound transmitting transducer the choice, the impedance matching network choice as well as the transmitter condition message control based on Lab VIEW. The system can be customized according to your demand to choose whether launching continuous or pulse signal, and it will further implementation on launches amplifier power, signal forms, impedance matching network parameters. The result of actual tests shows the underwater acoustic broadband amplifier signal generator and controller system could reduce the hardware expenses, also the system is advantageous for the promotion by using simple operation.
