Abstract

The purpose of this paper is to report experimental results in which multifrequency signals were transmitted, in a plane wave format, through scattering objects and the Rytov method of inverse scattering was utilized to calculate the real and imaginary parts of the refraction index under the assumption that variations in density were absent. The use of multiple frequencies allows subsequent analysis for frequency dependent attenuation and absorption and ultimately may allow for the solution of not only compressibility but density variations. Although in the experiment described by this paper, pseudo random noise was used as the multifrequency source, this technique represents only one of several methods which could be used for generating multiple and simultaneous frequencies.
