Diffraction tomography method applications in wide frequency range

Development of millimeter wave and microwave tomography for nondestructive testing and subsurface investigations is suggested. It may be manufactured as well in waveguide modification as in quasioptical one,:Description of th e main principles of creation of the tomographic system,both for millimeter waves band and for microwaves is given below. The system combines possibil ities as well of tomograph operating "on passage" as tomograph operating in regime of undersurface measurements. Using both of these approaches will a llow us to create microwave or millimeter wave tomograph providing:the imag e reconstruction of the object under investigation. The suggesting version of tomography is orientated towards applications in industry, medicine, detection and identification of abandoned objects and o ther fields.
