In Russia, it presented cellular radio absorbing material PRM-CA-N

In mid-July the Izhevsk radio factory (IRZ) He took part in the IX International Maritime Defense Show. Among other things, NIHD has introduced a new radar absorbing coating PRM-CA-N. It is about cell structure with enhanced absorption of radio waves.

In Russia, it presented cellular radio absorbing material PRM-CA-N

"Military Review" has decided to talk a little bit about the different types of RPM, what they do and where to apply.

absorbing materials (RPM) designed to convert electromagnetic waves into other forms of energy. Ways to do this there are a few, including absorption or scattering. By virtue of this PRM used as coverings for different surfaces: they reduce the coefficient of reflection of electromagnetic waves.

Divide absorbing materials can be of two types - narrowly- and a wide-range. The former are usually created from various types of plastics or plastics. In the case of using the second ferromagnetic, it is introduced into the insulation layer, consisting of a non-magnetic dielectric. Besides, increase the coating efficiency can be, applying several layers in a single reservoir.

Structure PRM may be either homogeneous, or not, may include, for example, gratings.

It is worth noting, that radar absorbing materials are not completely opaque. So talk about the aircraft-"stealth" largely unfounded. In the same time, depending on the material, you can achieve a significant reduction in the ESR facility, that can help make it less visible to radar.

There is another classification, which will help to better understand the types of RPM. They can be divided into resonance, non-resonant and nonresonant magnetic bulk materials. Resonance reflect radiation, depending on their properties, in whole or. Nonresonance include ferrite, which allows radiation to dissipate over the surface. non-resonant bulk, due to the large number of layers, absorb most of the rays, aimed at the object.

The Russian Defense Ministry publishes in his own classification of the site. It divides the PRM to absorb, interference and combined.

The most promising absorbing materials, It noted in the following note:, aerosil and a modified graphite. Their armed forces are used in masking means in the form of aerosol systems, additives to foams. In the form of aerosol systems PRM may be injected into the cloud of smoke. They are added to pyrotechnics smoke bombs and grenades, and foam. Through this aerosols and foams are additional masking properties.

modern RPM, in particular, used to cover missile warheads, which reduces the likelihood of their detection, and also increases the efficiency of overcoming the enemy's air defense systems. They can be used in the form of coatings, and cellular structural materials (cm. development of the Izhevsk). Due to their diversity and the emergence of new types of radar absorbing materials their production occupies an increasingly important place in the military-industrial complex and the defense of Russia.
