Abstract

This paper presents ambiguity functions for diffraction tomography using back-and-forth propagation. Both depth and lateral ambiguities are studied. The ambiguity functions corresponding to two different schemes for data acquisition are derived. We show that both the depth and lateral ambiguities are dependent on the wavelength of the insonification, and the range of values of the incident angles employed. Projections obtained by rotating the transducer give different ambiguities in two lateral directions. Projections obtained by rotating the object give less lateral ambiguity but greater depth ambiguity.
