스텔스 기능을 갖는 위장막의 RCS 특성 해석

다국어 초록 (Multilingual Abstract)

In this paper, radar cross section(RCS) characteristics for camouflage net are analyzed. Camouflage net is one of solutions which is used for stealth applications in fixed earth weapon or non-stealth weapon system to conceal the tank or military truck. To calculate the attenuation and RCS characteristics of camouflage net, the thickness, relative permitivity and permeability of camouflage net are investigated as design parameters. We used the locally planar approach to calculate the electromagnetic field because the wavelength of the detecting radar is longer than the thickness of camouflage net. From the simulation results, we know that the increase in thickness, the small imaginary value of relative permitivity and permeability could provide the better performance of RCS reduction. Also we have a conclusion that the design parameters of camouflage net must be optimized to obtain the desired RCS performance.
