Emulation research about feasibility of reducing dihedral corner reflector RCS with plasma

A dihedral corner reflector has a wide-angle dispersion characteristic, and it is a primary scattering position in certain orientations of a metal body. Furthermore, the technology is quite complex for its radar cross section (RCS) to be reduced. The paper first investigates the technological feasibility of reducing its RCS with plasma. Then, the RCS variations of a metal corner reflector when its surfaces are covered with plasma are analyzed by software emulation (the experimental equipment is being developed). The results show that the plasma has strong electromagnetic wave absorption characteristics. In addition, the attenuation of RCS declines with increasing incident wave frequency when the plasma. frequency and electron collision frequency remain steady. The results show that application of a plasma has practical engineering value in terms of reducting the RCS.
