摘　　要：针对连续Duffing混沌系统在检测多频正弦信号中存在的参数调节困难问题,数学方法证明了离散Duffing混沌系统设计的可行性,并建立了离散Duffing混沌系统。MATLAB环境下的仿真实验结果表明,通过软件可以实现调整离散Duffing混沌系统参数的目的,并且可以有效地检测出多频率正弦信号。When continuous Duffing chaotic system detects weak signals, it is difficult to adjust parameters. In order to solve this problem, a discrete Duffing chaotic system is established in this paper and the feasibility of this chaotic system design is also proved by mathematic methods. The simulation results in MATLAB environment show that this method can adjust parameters of Duffing chaotic system by using the software and can detect the multi-frequency weak sine signals effectively.
