Abstract
A system and method is disclosed for generating ultrasound results having a simulated level of porosity for a composite. Data for a set of composite coupons having different levels of porosity is obtained. An attenuation distribution function is fit to a back wall signal generated from the data for each coupon and a library of echo patterns based on such data is created. An interpolated attenuation distribution function is calculated based on an interpolation of two stored attenuation distribution functions having the closest porosity values to the selected level. A main attenuation distribution function value is assigned to one portion of a selected region in a zero porosity coupon and attenuation distribution functions values within a predetermined percentage of the main attenuation distribution function are assigned to other portions of the region. Waveforms associated with the portions are modified based on such values and selected echo patterns from the library.
