Abstract
A broadband multilayer radar absorbing coating (RAC) operating within the frequency range of 7–12 GHz was designed and fabricated for the purpose of a radar cross section (RCS) reduction of complex naval targets. The proposed RAC consists of three layers: a shop primer, a main absorbing material, and an epoxy resin paint. To validate the effect of a RCS reduction, the proposed RAC was applied to the life-size mock-ups of a periscope and snorkel of a representative submarine type. The RCSs of the two mock-ups with and without the RAC applied were measured, and the results compared with the simulations. The experimental results demonstrate that the proposed RAC guarantees an RCS reduction of 10–15 dB from 7 to 12 GHz. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1907–1910, 2014
