摘　　要：将常规互相关检测方法与混沌检测方法相结合,发挥各自的优势构成一个新的微弱正弦信号检测系统。理论分析及仿真实验表明该检测系统对被强噪声覆盖的微弱正弦信号非常敏感,对任何零均值噪声具有极强的抑制能力。With the synthesis of traditional cross-correlation detecting method and chaotic detecting method, a new weak sinusoidal signal detecting system is constituted,where the two methods can play respective preponderance.Theroy and simulation study have shown that this detection system is very sensitive to weak sine signal under strong noise and can effectively restrain any strong noise which has zero mean.
