混沌信号发生器在信息加密、保密通信、雷达系统等领域具有重大的应用价值。基于Proteus 虚拟实验平台，以AT89C51单片机为核心，给出了一种混沌信号发生器的数字硬件实现方案。以R?ssIer系统方程作为数学模型，采用四阶Rung-Kutta算法离散化得到数字信号，再通过D/A转换、I/V转换及电压放大电路产生混沌信号。 Proteus仿真结果与电路实验结果一致，验证了该方案的可行性。

Chaotic signaI generators have significant vaIue in information encryption,secure communication and radar systems.A digitaI hardware reaIization approach of chaotic signaI generator is proposed using AT89C51 SCM based on Proteus virtuaI experimentaI pIatform in this paper.R?ssIer system equations are seIected as a mathematicaI modeI,which are discretized using fourth-order Runge-Kutta aIgorithm to obtain digitaI signaIs,and chaotic signaIs are generated through D/A convert-ers,I/V converters and voItage ampIifiers.Proteus simuIation resuIts are consistent with the hardware circuit and the feasibiIity of the proposed method is verified.
