Resumo

This paper has described the radar ab sorbing materloin characterization andradar cross sectionme asurements, in the frequencyrange of8 to 12 GHz, using a very simple setup. Simple targets like sphere, cylinder flat plate, and dihedral corner were characterized by measuring the backscattered radiation patterns when these targets were illuminated by monostatic microwave radiation. Aleasuremeras were carried out inside an an echoic chamber (9x5x4m(3)). Typical radar cross section patterns' were obtained in different aspect angles', by rotating the targets around their vertical axes. The measured values and the theoretical previsions for each metallic target showed that the used setup guarantees a good precision of the obtained data. By recovering one of the targets, a cylinder, with a specific radar absorbing material developed at Materials Division of the Brazilion _tleronautics and Space Institute, it was possible to compare the obtained patterns and to discuss the influence of radar absorbing materials on the observed radar cross section reduction patterns'. The used methodology showed to be useful for attending aeronautical and telecommunication applications. (AU)
