Abstract

A set of automatic operations of hydroacoustic broadband arbitrary signal source system is introduced. VC++ is used to design filter and the desired signal on host computer, it could be always adjusted the parameters to generate the signal that meets the need. The upper computer together with dedicated capture cards, decoder circuit, and relay achieve controlling over the matching circuit of the transmitter, choosing transducer, matching 0.004~1.0Hz (normalized) broadband signal. The upper computer, dedicated capture card, relay as well as class AB amplifier circuit achieve controlling over power amplifier circuit of the transmitter, namely, amplifying and transmitting the analog signal. A method that achieves automatic operation of hydroacoustic broadband arbitrary signal source system is given, it is able to reduce the long time repeat operations for the operators, and solve human resource issue in engineering practice.
