Abstract
The results of the study of the values of the reflection coefficients and the effective scattering surface of the developed design of the electromagnetic radiation screen in the frequency range of 2…12 GHz are considered. The structure consists of a layer of moisture-containing pseudo-oval scattering elements with linear dimensions of 1…4, 1…2 and 10…20 mm, which is placed between two layers of polyurethane sealing mastic. The use of pseudo-oval elements with linear dimensions of 1…4 mm containing solutions made on the basis of a 20 % solution in the developed electromagnetic radiation screen design allows reducing the values of the reflection coefficients of electromagnetic radiation at frequencies 4.2…6.5 and 1.0…4.1, 8.0…12.0 GHz. The formation of a screen design based on elements with linear dimensions of 1…2 and 10…20 mm, impregnated with a 20 % sodium chloride solution, leads to a decrease in the values of reflection coefficients in the frequency range of 2…12 GHz. It is established that the values of the effective scattering surface of ground objects in case of placing or fixing of the specified design variant of the electromagnetic radiation screen on their surface are 0.6…24.0 m2 in the frequency range of 2…12 GHz. This makes it significantly difficult to obtain reliable information about the location and characteristics of ground objects in the frequency range under consideration.
