Ferrite radar absorbing material

The new Russian anti-radar materials The Russian researchers go further for developing more advances compounds and technologies for an anti-radar covering. As it's well known, the airframe and the shipframe stealth geometry gives only a partial answer for the contemporary radar development. Only the centimeter and millimeter long radar waves are effectively deflected by such method while the L-band radars progress is remained the growing treat for military devices. Other complimentary methods are composite use and covering.

The usually used antiradar materials are the resins and paints with ferromagnetic. The new nano-metric anti-radar covering is much more light and stable. It's made with magneto-dielectric layering 2-80 nm thick on a high temperature-steady material. The radar-absorption is about 10 Db in 8-80 GHz diapason, i.e. lg (P1/P2) = 1, while P1 – is the incoming radar power and P2 – the reflected. By the formula with these materials the RCS can be reduced 10 times. Its relative mass is as 1 – 1.5 kg/m2. High resistance against climatic factors is provided. They have the one-layer structure instead of usually 5-6.

This new technology can be used not only for RCS reducing, but for side-lobe radiation reducing on the radars, raising their effectiveness. The military electronics can be defended from radio splashes and an unsanctioned communication access by this way. Personal isolation from the dangerous radar microwaves can be provided too by this method.

The potential of this technology allows creating ant-radar materials with working diapason of 1 – 300 GHz. The implementation of it on the 4th+ generation fighters' fleet could prolong its service while the 5th generation planes are yet to be produced or too costly for some customers.
