Summary on Weak Signal Detection Methods based on Chaos Theory

摘要：

Definition,significance and traditional method of weak signal detection(WSD) are introduced.Content of WSD methods based on chaos theory is sorted in detail. Theory base,principle and main content of WSD method based on chaos oscillator are introduced.Its main content contains detection task,detection system,detection condition,chaos criterion,method improvement and method realization.Detection task is to measure parameters of the various periodic signals to be detected.Duffing oscillator is usually used as a chaos detection system and would have different detection performance with different equation form.Detection condition includes noise condition and initial condition.Noise condition means noise type and SNR.Chaos criterion is about identifying and describing state of chaos system.Hardware realization includes design of chaos measurement circuit and sometimes with DSP. This WSD method can be combined with traditional WSD method for lower SNR..
