Study of Radar Weak Signal Detection Method Based on Duffing System

The kinetic behavier of the Duffing system is analyzed. The state changes of the Duffing system are studied. The main process is composed of the inner orbits state, the bifurcation state, the chaotic state, the chaotic critical state and the large-scale periodic state. Let the weak signal of the noise be the trigger condition that change the inner state of the Duffing system, the Duffing system applied in the weak signal detection is discussed. At last, the validity of this method is validated by the simulation.
