| Abstract: | A prototype of simulation transmitting system has been designed based on the frequency spectrum characteristics of typical ship radiation noises.The design includes signal structure,transducer choice,system constitution,etc.The system has a capability of generation noises underwater with a frequency range from 100Hz to 16kHz,including continuous spectrum and special line spectrum.The distribution and shape of frequency spectra are controllable,and the dynamic range of noise source level is up to 60 dB. |
