Abstract: The conference paper discusses modifications to the standard synthetic aperture focusing technique for improved imaging of concrete materials. Experimental evaluation was performed on three modifications to the velocity estimation, direct wave suppression, and attenuation compensation methods. Results show potential for improved performance beyond the standard imaging methods. Authors: James A. Bittner, John S. Popovics Full read more
