Wavelet Based Cumulant Processing
Abstract
The objective of this program is to develop appropriate time- frequency signal processing methods for the analysis of the transient response of mechanical systems and structures. The focus of this program is on mid- frequency (2-20ka) target strength measurements. At higher frequencies, structures of interest respond primarily as rigid, or inelastic, scatterers. However, in these same structures at the mid-frequency and lower ranges, significant structural vibrations in the form of traveling waves can be created by the incident sound pressure. These traveling waves in turn cause sound to be reradiated from the structures in a rather complicated fashion at significant sound pressure levels. This reradiation is referred to as elastic scattering.
