Abstract: In allusion to distilling signal under the chaos background,this paper put forward phase matched separate method in order to clean chaos background.The method is differ from other methods.It neither reconstructs phase to beforeh estimate chaos nor makes geometry analysis of chaos in finity dimension phase space.The method efficiency was validated via imitation under sine signal of different amplitude and phase in chaos background.The separating effect is distinct via separating degree analysis.
