Application of wavelets to scattering for wavepacket synthesis
Charles F. Gaumond · Acoustics Research Letters Online · 2000
A novel nonlinear, continuous wavelet transform filter is developed to separate short-time and narrow-frequency components from a set of broadband echoes from a finite cylindrical shell. The components are caused by specific physical phenomena and are called wavepackets. Two wavepackets sometimes overlap in time and frequency, which makes wavepacket synthesis more difficult.
