Characterization and Reduction of Bistatic Radar Cross Section of Hollow Cylindrical Cavity

Abstract

Open ended cylindrical cavities occur in many places of large complex structures. Hence Radar Cross Section (RCS) characterization of this structure is quite important. In this article characterization of bistatic RCS of an electrically large, open ended cylindrical cavity using the shooting and bouncing ray approach is carried out. Next, the structure is wrapped (both inside and outside) with a transparent and flexible metamaterial absorber made of Indium Tin Oxide (ITO) coated Polyethylene Terephthalate (PET) substrate and reduction in bistatic RCS is observed.
