摘要

舰船辐射水声线谱是被动声纳进行目标参数估计和类型识别的主要依据,传统的隔振系统无法改变系统线谱特征,对舰船的隐身性能构成了严重危害。根据线谱混沌化原理和舰船隔振系统的特点,提出了参数扰动广义混沌同步化线谱控制方法,能够使系统在小能量条件下转变为混沌运动状态,达到削弱线谱强度和改变频谱结构的目的,数值仿真验证了该方法的有效性。

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.
