A method of weak signal chaotic detection based on Labview

摘要

In this paper, a method of weak signal chaotic detection based on Labview is proposed. The method solve Duffing equation using powerful numerical calculation function of Labview, then the timing diagram and phase diagram of this weak chaotic signal are given by the virtual instrument. The results show that the experimental results by Labview are consistent with the theoretical simulation results by Matlab, and the method is an effective detection method. Compared with the traditional method of the weak signal chaotic detection, it has many advantages, such as a convenient parameter changing, easy realizing, high accuracy, good real-time capability and so on. The realization of the weak signal chaotic detection has been provided a new way.
