提出了基于连续混沌时间尺度变换的连续混沌调频信号动力学设计理论,并以Colpitts电路为例给出了具体的实现模型.通过吸引子重构和Lyapunov指数分析,阐述了连续混沌调频信号的动力学特性.结果显示连续混沌调频信号的最大Lyapunov指数与混沌信号的最大Lyapunov指数相同;连续混沌调频信号的动力学设计实现方式简单且系统参数易于控制,同时信号形式与数学意义上的连续混沌调频信号保持一致.
The design theory of continuous chaos FM signal based on time series transformation of continuous chaos is put forward and the concrete realization model is given by taking Colpitts circuit as an example.The power of continuous chaotic FM signal is expounded by attractor reconstruction and Lyapunov exponent analysis The results show that the maximum Lyapunov exponent of continuous chaotic FM signals is the same as the maximum Lyapunov exponent of chaotic signals. The dynamic design of continuous chaotic FM signals is simple and the system parameters are easy to control. At the same time, the signal form and mathematical chaos FM The signal is consistent.
