摘　　要：本文提出了一种利用Labview实现微弱信号混沌检测系统的方法。基于Labview的虚拟仪器平台,采用四阶-龙格库塔法对Duffing方程进行求解,通过识别系统相平面轨迹的变化实现微弱信号的检测。实验结果表明,利用Labview设计实现的检测系统产生的实验结果与MATLAB理论仿真结果一致,该系统具有参数调节便利,易于实现,可作为子VI嵌入到其它系统进行二次开发,仿真结果证实了该方法的可行性。A method of weak signal chaotic detection based on Labview is proposed.Based on the virtual instrument platform of Labview, using the fourth-order Runge-Kutta method to resolve Duffing equation.The weak signal is detected by the phase transition of chaotic Duffing system.The experimental results by Labview is consistent with the theory of simulation results by Matlab.This method is characterized by the feature of convenient operating parameters and easy to achieve.This method can also be used as a subvi embedded into other systems for secondary development.The simulation results show that the method is feasible.
