ABSTRACT
Electromagnetic radiation interacts with electro-physical inhomogeneities in the propagation medium. In contrast to electromagnetic radiation, acoustic radiation interacts mainly with density contrasts in the sounding medium. The attenuation of electromagnetic waves in a water-filled medium is rapid, which hardly attenuate in such a medium, as water is practically incompressible and transmits acoustic oscillations without significant attenuation. Ultrasound is used in parking sensors and for control of industrial robots. The ultrasound system used by bats is perhaps the only ultrasonic ranging system actually effective in air. The chapter presents an development of physico-mathematical models of a system for reconstruction of images of inhomogeneous media based on tomographic processing of multi-angle measurements of scattered acoustic radiation; the development of the key elements of a simulation system and the development of experimental measuring techniques; and finally, an evaluation of the potential and actual characteristics of an acoustic wave tomography in different measurement and sounding schemes.
