Abstract :
Physical Optics (PO) is used to calculate Radar Cross Section (RCS) of flat plate and dihedral corner reflectors. The numerical results obtained via simulation are used to compare the RCS measured for these targets recovered and non-recovered with Radar Absorbing Materials (RAM). All simulations and experiments are effectuated in a frequency of 10 GHz. Experimental measurements using Radar Cross Section (RCS) confirm the accuracy of the analytical calculation for flat plate and dihedral corner reflectors. The RAM performance is analyzed for each target separately. The RAM used to recover the flat plate and dihedral corner was developed at Divisao de Materiais IAE/CTA.
