Effect of combat textile cloth on human radar cross section for microwave camouflage applications

Abstract

This article proposes an analysis of the effect of combat textile cloth on human radar cross section (RCS) for microwave camouflage applications. Based on numerical simulations for the definition of the geometric profile of the human body and the measurement of electromagnetic parameters of the fabric, made by cotton and polyester, the work reveals that the uniform has a direct influence on the absorption of electromagnetic waves from a hypothetical ground surveillance radar (9.375 GHz). The results of 360° measuring human RCS showed that it can be attenuated, on average, by approximately 8 dB due to the effect of the material.
