摘要：
This paper deals with a new method for feature extraction of target signal. The signal is first decomposed by wavelet transform, and on the base, the decomposed coefficients are reconstructed to form a new time series, from which some energy parameters can be extracted by time-domain analysis. The effectiveness of the method is verified by a real target signal with additive simulated noise signals.
