摘要
分析了当前微弱信号检测领域中常用的三种检测方法,提出了将混沌技术应用于微弱信号的检测,阐述了基于Duffing混沌振子的微弱信号的检测原理和过程,给出了Matlab的仿真实验结果,理论分析和仿真表明该方法简单、有效、易于实现。
In this paper, analyses three detection method in weak signal detection domain, and then put forward the chaos detection technology. The principle and process of detecting weak signal by using chaotic oscillator are discussed in detail. In addition, the simulation results based on Matlab are given, the theory and simulation experiment show that above method has many merits such as simple, effective and easy to be applied.
