ABSTRACT
This chapter discusses typical example of inverse problems solutions occurring in radio physics related to other applications. A classical inverse problem takes place when an image is reconstructed with spreading. The basic form for presenting three-dimensional (3-D) images in geolocation and radio tomography is a 3-D cube. The contouring of equipotential surfaces is one of the techniques available for the visualization of 3-D images. The result of contouring is a three-dimensional surface, which can be visualized by the standard techniques of 3-D polygon graphics. The proposed techniques for visualization of 3-D tomograms entail the presentation of results as a polyscreen, equipotential surfaces, and orthogonal cross-sections in the form of bitmap images. The results of 3-D tomography in the form of 2-dimensional bitmap images can be displayed in a visually more accessible form as a video record or an animation built up from successive sections, layers, or records of camera motions around the object.
