Design of Ship Radiated Noise Signal Generator Based on FPGA

摘要

The rapid development of FPGA provides a new platform for target signal simulation. Firstly, the components of ship radiated noise are analyzed in the paper. Then a module of ship radiated noise signal generator based on FPGA is designed, generating 20Hz-10kHz frequency band noise to simulate ship radiated noise. Finally, two kinds of signal are used to test the generator module, and the performance is in line with expectations. The generating module can be used as a sound source in noise experiment and can also simulate underwater targets.
