SUB-JOURNAL
"FOREIGN RADIOELECTRONICS. SUCCESSES OF MODERN
RADIOELECTRONICS"
Monthly international radioengineering journal of Popov's technical society in
radioengineering, electronics and automatics. Found in 1947, the journal is subscribed in all
CIS countries, and also in Germany, USA, Japan and other (it is total 15 countries). The
Journal regularly publishes the reviews on specific areas of modern radioengineering science,
original papers dedicated to perspective applications in various spheres of activity, last news
in radioelectronic science and technology. The materials published in the Journal can appear
useful for the chiefs and experts of the enterprises for planning technological, financial,
investment politics. The Journal regularly organizes competitions for young scientists and
post-graduate students.

Reconstruction of Microwave Images of the Subsurface Objects by Diffraction
Tomography and Stepped-Frequency Radar Methods The reconstruction of microwave
images of the subsurface object cross-sections by the diffraction tomography method and by
method of SF radar (stepped-frequency radar) is considered. In both methods in the
reconstruction algorithms the apparatus of Fourier transformation are used. The images
obtained by the considered methods from experimental data were compared. It is shown that
good images of dielectric and metallic objects of different shape, which are located under
ground, can be obtained by the considered methods. The diffraction tomography method is
preferable in the case of imaging of complex cross-section of object studied. The results of
electromagnetic simulation on imaging of the subsurface objects are also given in this paper.
