Abstract

Line spectra are the most visible signs of marine vessel radiate noise spectra, which can be detected, tracked and identified by passive sonar. Since the feature of line spectra could not be changed by traditional isolation system, and hence it is harmful to the acoustic stealth of marine vessels. According to the principle of line spectra chaotification method and the characteristics of the vibration isolation system, a new method of generalized chaos synchronization based on parameter perturbing is introduced. The numerical simulation results show that this method can make the system change into chaotic state with tiny energy, furthermore, the intensity is weakened and the line spectra structure is changed.

Key words

parameter perturbing / chaos synchronization / line spectra / vibration isolation.
