Abstract

The investigation on the reduction of radar cross section (RCS) has been an interesting research subject in recent years. Plasma-based stealth is a RCS reduction technique associated with the reflection and absorption of incident EM wave by the plasma layer surrounding the structure. In this paper, an overview of the plasma stealth has been presented. The MCNPX codes are employed to calculate the density electron of air in STP conditions by the alpha decay. Then, the RCS of the flat conductive plate, in the presence and absence of plasma coatings created by alpha decay of nuclei, is simulated by FEM solving method in CST-studio. The most important aspect of the research is the attempt to optimize the RCS reduction by changing the plasma parameters created by the radioactive nuclei. The obtained results show a reduction of 7 to 11dB at RCS in the typical radar frequency range (2 to 12 GHz).
