| 摘 要： | 该文采用Wien电桥产生了基于双卷吸引子的混沌二相序列,通过PSPICE模拟及计算,分析了电路参数对混沌二相序列的随机分布及相关特性的影响。结果表明在参数选择适当情况下,该混沌二相序列的主要性能优于基于Logistic映射的二相序列,与Bernoulli序列相近,非常适于作为雷达波形。

| Abstract: | Chaotic binary sequence based on double scroll attractor is produced by Wien bridge in this paper. Effects of the circuit parameters on the stochastic distribution properties and the correlation property of the proposed binary sequence are analyzed by means of the PSPICE simulation. The results show that properties of the binary sequence is better than that of the binary sequence based on logistic map and is similar to that of Bernoulli sequence so long as selecting parameters properly. It is suitable for the radar waveform. |
