in this paper we use fusion technology based on Rossler chaotic oscillator and proportional differential control technology to detect the frequency of the weak signal. The dynamic character of Rossler equation is analyzed and it is immune against the white noise and the interference signal having larger frequency difference with the intrinsicfrequency of chaotic oscillator. And proportional differential control is used to regulate the system to periodic state and the method of spectrum analysis to detect the unknown frequency. The simulation result verified that the presentedmethod is effective and it is very feasible.
