Application of Method of Spectral Component Ratio of Wavelet-Packets to Discrimination between Earthquakes and Nuclear Explosions

The spectral analysis method is widely used in discrimination between nuclear explosions and earthquakes. As a stationary method, it has low resolution due to its invariable time‐frequency window, even if the Gabor transform is adopted. To improve its resolution, a wavelet transform is applied to th...
