Abstract: Jet engine intake is an important scatter source of vehicles. A research of EM scattering characteristic for intakes of different sections and shapes using shooting and bouncing rays (SBR) approach is presented. A radar cross section of dihedral corner reflector and a practical intake are calculated by using this method. Good agreement between computation results and measured data shows that SBR is an effective method.

Key words: flight vehicles, air intakes, radar cross sections, electron magnetic scattering
