Abstract
Aiming at the requirement of underwater acoustic equipment, such as the simulation design of interference signal of torpedo sonar and other underwater acoustic equipment, an underwater acoustic radiation noise simulation equipment is designed. The design process of the simulation device is introduced in detail from the aspects of system composition, working principle, hardware structure and software. The hardware system of the simulation device uses ARM as the control core, extracts noise data from external storage devices, applies mature USB-OTG high-speed data transmission technology and hardware programming technology. Modular hardware and software circuit design technology, adaptive linear power amplification technology and broadband Transducer technology to achieve high-power, high-fidelity emission of broadband noise, overcoming the shortcomings of high price, complex structures and poor reliability.
