The Use of Corner Reflectors to Simulate Tactical Aircraft

Abstract

Using the methods of mathematical modeling, the values of the radar cross section (RCS) of the Su-27 aircraft model and trihedral corner reflectors in the high-frequency wavelength range were obtained. The scattering characteristics are estimated for trihedral corner reflectors that used as the main scattering element in the proposed model of an airborne radar decoy. The presented results show that in order to obtain sufficiently high values of the RCS of a radar decoy when probing from the front hemisphere, it is necessary to use a “quadruple” corner reflector. If it is necessary to simulate the exact median values of the RCS of a real object in a narrower range of irradiation angles, then it is better to use one tilted corner reflector. It is reasonable to use the obtained results at the developing aerial decoys to simulate the scattering of various complex aerodynamic objects, if corner reflectors are used as a reflective element.
