The frequency characteristic of chaotic synchronization systems and weak signal detection
The mutual synchronization of chaotic systems is considered. It is proposed to use the concept of frequency domain. A simple model to measure the frequency character is designed and the characteristic curve of a Chua chaotic synchronized system is obtained. Some results from theoretical analysis and numerical simulation indicate that the system possesses a multiband of frequencies with distinct features shown in each band. Thus, it may offer various resources of frequencies. In particular, it is capable of detecting weak signals drowned in noise in some bands.
