НОВІ НАНОСТРУКТУРНІ ФАРБОВІ АНТИРАДАРНІ ПОКРИТТЯ ТА ОСОБЛИВОСТІ ЇХ ВИКОРИСТАННЯ

Abstract

Modern stealth technologies are aimed at the development of methods that ensure a reduction in the visibility of objects of military techniques (OMT), buildings, personnel, etc. in the radio-technical, infrared and other relevant ranges of the spectrum of electromagnetic radiation in which surveillance is carried out, and thereby increase their survival in conditions of hostilities. These methods are based, in particular, on the use of special materials and coatings that absorb ultra-high-frequency and infrared radiation, as well as specially developed geometric shapes of the surface of OMT, which favour to reflect the radar wave, laser beam or thermal radiation, away from the receiver. Another way to reduce visibility is the use of radio-transparent structural materials. In a complex application, the above countermeasures against radio-technical and optical-electronic means of detection, aiming and pointing lead to a sharp decrease in the power of the reflected signal in the direction of surveillance devices.

The purpose of the work is to analyze the possibilities of effective use of new paint anti-radar coatings developed at O.O. Chuikо Institute of Surface Chemistry of National Academy of Sciences of Ukraine.

Specialized modern laboratory installations and devices were used to characterize radio- and IR-absorbing materials and coatings. In particular, we used: an installation for measuring the reflection coefficients of electromagnetic waves, an analyzer of antenna-feeder devices AFU: 2 MHz − 4 GHz (model S331E), a laser device for measuring the distance LRM 1500M, a digital thermal imaging observation device ARCHER TMA-55M, an induction thickness gauge, a climatic camera.

The possibilities of effective use of coatings were experimentally investigated. The results of the analysis show that the operational parameters of the coatings make it possible to reduce the radar visibility of OMT, buildings, structures, etc. The function of protection in the IR range and the compliance of the coatings with the requirements for application in the aviation, missile and naval fields require further research. However, the use of developed protective coatings can be appropriate for masking «weak spots» of side and deck structures of a special geometric shape of modern inconspicuous ships, etc.
