摘要
混沌系统的参数敏感性和初值敏感性可以用于小信号检测 ,抑制噪声是其关键。根据符号动力学的理论 ,提出用耦合多个混沌测量系统同时进行相关测量来控制噪声的机制。研究了具体的耦合混沌测量系统 ,在理论分析的基础上 ,数值实验表明这是一种可行的全新测量机制 。
The parameters sensitivity and initial conditions sensitivity of chaotic systems can be used to detect weak signals, and the noise reduction plays a key role in its realization. A new measurement model is proposed that the noise can be reduced by coupled multi chaotic measuring units to detect noisy objects simultaneously,and a coupled system is studied theoretically and simulated numerically. The results show that the new machine for reducing noise is effective. It is very significant for future theoretical and experimental study.
