Design of Multi-Layer Radar Absorbing Coating and Transparent Shielding Film for RCS Reduction of Complex Targets
A broadband multi-layer radar absorbing coating (RAC) and transparent shielding film (TSF) operating within the frequency range of 7 to 12 GHz are designed and fabricated for the purpose of a radar cross section (RCS) reduction of complex naval targets such as submarines and ships. The proposed RAC consists of three layers, a shop primer, a main absorbing material, and epoxy resin paint. In addition, a TSF was fabricated by coating an ITO/Ag/ITO multilayer on a polyethylene terephthalate (PET) substrate using roll-to-roll DC plasma deposition technique. The experimental results demonstrate that the proposed RAC guarantees an RCS reduction of 10 to 15 dB from 7 to 12 GHz.
