Investigating the role of electromagnetic absorption ferrite coatings in radar detection of high speed crafts

Electromagnetic absorption ferrite coatings are used in two important military and medical fields. The importance of these coverings in the military field is to hide military equipment and secure them as far as possible from the enemy's throws. A large part of the projects related to the design and construction of crafts is intended to reduce the radar cross section )RCS(, which uses structural body changes to achieve this purpose. Body deformation will have a lot of difficulty and problems, most notably the weakening of aerodynamic properties. The radar absorbing coatings and their installation on the crafting bodies, in addition to maintaining optimal design, can weaken and absorb a wide range of radar waves, which will lead to realization of them. Nano-material is an excellent choice for absorbing electromagnetic waves due to its unique electrical and mechanical properties. Nano-based composites can be low-weight, cheap and easy to synthesize. The use of nanoparticles iron, nickel and cobalt in the manufacture of ferrite nano-composites is capable of reducing the radar cross section area by at least 6 times in the frequency range of the radar, which is a very good result. The material is pulled by a 1 mm overlay on the crafts body and is able to hide them from the enemy's radar's sight.
