Development of technologies for creating materials, environments and coatings with specified electrophysical characteristics for practical implementation in production and widespread use of observability attenuation technologies of surface, air, space, abovewater objects, surface-based installations, troops for the needs of Armed Forces of Ukraine and other military formations, impacts of artificial sources of electromagnetic radiation on the human body today is especially relevant.
Nowadays, "stealth technologies" include the following main areas: the theory of diffraction on bodies of complex shape, research and development of radio-absorbing materials, coating technology and, finally, radiophysical experiment, which is used for control in each of these areas. One of the most important tasks is to reduce the level of signals generated by the reflection of electromagnetic waves emitted by radars, since radars still remain the most "long-range" means of detecting targets and air defense systems aiming.
To date, "stealth technology" begins with mathematical modeling of electromagnetic wave scattering on an object, the radar visibility of which should be reduced. This step is essential for a preliminary assessment of the possible result and allows optimizing the shape and electrophysical characteristics of the object.
The world leading countries have developed absorbing materials that capable to provide electromagnetic compatibility of the electronic equipment, camouflaging and counteraction to radio technical intelligence, use in designs of the radio electronic equipment.
The comparative analysis of the developings that are promising for usage as radio-absorbing materials and radio-absorbing covering is carried out in the work.
In the future, it is planned to expand the shielding frequency range and the range of use of absorbing coatings to protect personnel and equipment from electromagnetic emission.
