混沌振子弱信号能量检测方法
Chaotic Oscillator Detection Method for Weak Signals
摘要
Abstract
A novel Duffing detection method based on energy separation algorithm is proposed.The frequency distribution characteristics of the Duffing system in different states are investigated and an identification method is obtained with the instantaneous frequency,then the selection rule of identification threshold is given.The noise immunity and real-time property of the method are analyzed.Simulations show that the algorithm complexity and real-time performance of the method are significantly improved and it can meet the needs of the weak signal detection under the strong noise background.关键词
