In this paper the method of extracting weak periodical signals form being merged in the background of Gauss white noise by use of the cycling auto-correlation approach was presented, which is aimed to solve the difficulties encountered in the practical usage of auto-correlation function in this aspect. Some results of simulation by computer to this approach were given at the end of this paper showing the forthright and the better real-time characteristic of this method.
