Figure 1From: Geometrical Feature Extraction from Ultrasonic Time Frequency Responses: An Application to Nondestructive Testing of MaterialsSimulations of the proposed model for Stochastic scattering attenuation. Simulation parameters of the ultrasonic pulse were central frequency = 500 KHz, fractional bandwidth = 75%, and mean scatterer size = 0.5, 1 and 1.5 mm. (a) = 0.5 mm, (b) = 1 mm, and (c) = 1.5 mm.Back to article page
