Knowledge in anti-radar coating technology is something that have to be mastered by Indonesian military. That’s because with the fast growing of radar technology, the position of military vehicle and weaponry can be known from the distance. Because of that, to support the national defence, especially in surveillance missions, it is required a technology to camouflage military vehicle and weponary so that it cannot be detected by enemy’s radar.
One of the technology to camouflage military vehicle and weaponry is by coating them using Radar Absorbing Material (RAM). In this paper nanostructure engineering of ferrite material has been done using ferrite phase alloy of BaFe(MnCo)1,5Ti1,5O19 to reduce radar electromagnetic wave. The material was tested using two method, free-space measurement and waveguide measurement. The measurement was done to know the S-parameter of the material and its reflectivity. From the test, it is known that for X-Band frequency range, the material in powder shape has an absorbtion of -16dB, and when the material was mixed with elastomer the absorbtion is dropped to -5,3dB.
