N2 - A novel method based on Hilbert Huang Transform (HHT) for analyzing the non-linear and non-stationary shock signal is presented. The frequency components of the shock signal are complicated, Empirical Mode Decomposition (EMD) can decompose the signal into Intrinsic Mode Functions (IMFs), and after Hilbert transform the instantaneous frequency of each IMF is obtained, then can get the physical meaning of each IMF, and so the physical meanings of the shock signal are becoming obvious. At last, this paper gives the results of the theoretical calculation, and also gives the marginal spectrum compared to the Fourier frequency spectrum.
