Abstract

Nowadays, camouflaging the warfare equipments particularly aircraft, helicopters and drones are inevitable. Camouflaging in the radar range means attenuation, reflection and dispersion of radar waves. This operation can be achieved by different methods most notably, by reducing the radar cross section or using radar absorbent material. In this study different NANOCOMPOSITEs were tested for loss of radar waves. As a result of this research poly-aniline NANOCOMPOSITE of iron oxide (III) nanoparticles and titanium nanoparticles were the most effective. Also a few experiments were carried-out on the thickness and percentage of NANOCOMPOSITE constituent. This work was carried out in three stages. In the first stage, Fe3O4 nanoparticles were prepared by co-precipitation method using NH3 solution. The crystal structures and morphology of nanoparticles were investigated and characterized by X–ray diffraction (XRD) and scanning electron microscopy (SEM). In the second part, conducting POLYANILINE/nanoparticles (TiO2 and Fe3O4) composites were synthesized by in situ polymerization method with ammonium persulfate (APS) as the oxidant and under an ice-water bath (0 °C). In last step, NANOCOMPOSITE powders was completely dispersed in paraffin and was followed by casting process on test plate. The RADAR ABSORBING property of NANOCOMPOSITE was investigated by vector network analyzer at the frequency range of 8-12 GHz. The best absorption was caused by the NANOCOMPOSITE with concentration of about 10% and thickness of 4 mm. Maximum reflections recorded was about 33.3 dB at 9.5GHz.
