An approach of the harmonic signals extraction from chaotic interference is proposed. Based on empirical mode decomposition and the concept that any signals are composed of a series of the simple intrinsic modes, and the chaoic interference signals are decomposed to a series of intrinsic mode functions, the harmonic signals can be extracted. Simulation results show the approach is satisfactory.
