Results of the Researches of Attenuation of the Energy of Electromagnetic Waves by Optically Non-Transparent Barriers
RÉSUMÉ
The results of experimental researches of losses of electromagnetic energy in the decimeter bandwidth after the waves propagation through the elements of building structures are examined from the point of view of the basic requirements set to the radar characteristics in terms of detection of people behind the optically non-transparent obstacles. The samples of building structures and construction materials representing the most probable options of obstacles during the man-caused disasters are selected as objects of research. Dependences of radio waves attenuation upon the frequency and polarization are investigated. Possibility of reception of the reflected electromagnetic signals in the decimeter bandwidth from moving living beings behind the concrete and armored concrete ceilings and walls is considered. The requirements set to the conditions of experiments and methodology of their performing are discussed. Authenticity of results is substantiated.
