摘要
在分析了混沌弱信号检测原理的基础上,提出了采用一组非线性微分方程组检测随机相位弱正弦信号的方法,并给出了理论证明.计算机模拟表明对随相弱正弦信号可以用16个方程检测到.
The theory of chaos-based detection is analyzed, then the method of using a group of nonlinear differential equations to detect phase randomly distributed weak signal is proposed and proved. Computer simulation indicates that the phase randomly distributed weak sinusoidal signal can be detected out by using 16 equations.
