Abstract
A pulsed ultrasonic collection facility was used to study the accuracy of a previous program which models pulsed ultrasonic wave propagation. The previous program modeling was initially reviewed for its validity and found to have a scaling factor error. This error was corrected before a comparison of the theoretical and the experimental pulsed response was conducted. The excitation studied was a circular piston impulse input. For proper comparison, the acoustic potential produced by the program modeling (at a given distance from the acoustic source) was expressed in terms of acoustic pressure. Two separation distances were used to compare the output produced by the theoretical modeling and the measured experimental response A general comparison of the experimental and the theoretical pulsed response appears to be in good agreement. The MATLAB program was used to perform all necessary mathematical computations and manipulations to produce a graphical representation of the collected data. The graphics program, AXUM, was used to compare the results graphically
