中文摘要：
隐身飞行器的核心目标是低雷达反射截面（RCS）、低可探测性.但飞行器表面存在诸如缝隙、台阶等不连续特征,这些特征会产生较弱的散射源,对雷达发现隐身飞行器的目标特征仍有影响.由于无装机的涂覆吸波涂层的阳极化铝板,实验室制备了雷达吸波涂层（RAM）.基于吸波涂层的特性,运用FEKO软件对弱散射源缝隙的雷达反射截面（RCS）进行了仿真分析.
英文摘要：
The core target of the stealth aircraft is low Radar Cross Section（ RCS）,low detectability. But the discontinuity on aircraft surface will produce weak scattering source,which still has an impact on the target characteristics of stealth aircraft on the radar. Because of not having anodized aluminum with wave absorbing coating on the real stealth aircraft,we developed the radar absorbing material（ RAM）. Based on the characteristics of wave absorbing coating,the weak scattering of Radar Cross Section（ RCS） was analyzed by software FEKO.
