摘要
Abstract
The traditional weak signal detection theory based on single Duffing chaotic oscillator system is described. In the traditional method based on chaos theory for detection of weak signals in strong noise environment, there prone to be instability in the phase change of system and the anti-noise should also be further enhanced. For solving the problems, the method of detecting the weak signal in strong noise environment based on double Duffing coupled improved oscillator system is proposed, and the weak sinusoidal signal detection in strong noise environment is finished the simulation by using this method. By simulation, the result is that based on the system of two-coupled improved chaotic oscillator, the weak signals in the strong noise environment can be better detected and the noise is better suppressed.关键词
