摘要
在分析了Duffing混沌系统动力特性的基础上,提出了不含系统策动力的混沌检测模型,结合信号的自相关检测技术,利用该检测系统可以实现频率已知但相位未知的正弦信号幅值的检测,仿真实验表明了该方法的有效性。
A new chaos detection model without driving force is presented based on the analysis of Duffing oscillator's dynamic characteristics.Combined with the self-correlation detection technology,the amplitude of sinusoidal signal with known frequency and unknown phase can be detected.Simulation experiments show that the method is effective.
