| Abstract: | The basic form of Duffing equation is firstly analyzed; and then. it describes the principle of weak signal detection based on the change of phase trace; the method of expressing Chaotic attractor by ways of bond wave and spiral in Chua circuit is presented, and then, a bond wart, synchronization syslem based on Chua circuit is designed; an application is put forward, which detects weak signal utilizing chaos bond wave synchronization system, the critical problems existing in weak signal detection based on chaos can be solved. The research provides the foundation of putting chaos bond wave synchronization system into practice application to weak signal detection. |
