In the analysis of underwater acoutic signal source and design of similar signal synthesizer, underwater acoustic signal was obtained by A/D converter. The obtained signal was separated to tonal components and broadband noises by the ATW algorithms. The noise generation filter, which can generate the noises similar to the analyzed broadband background noise, was designed by Hilbert Transform. After that, the system which can generate the signal which is similar to moving vessel noises is designed by synthesizing the generated noises and the analyzed tonal components. This system can be used to field maneuvers, and it can cheat enemies and escape from the tropedo attacks.
