涂敷介质目标的表面反射系数及其雷达散射截面

Calculation on the Reflection Coefficients and RCS on the Surface of the Target with Multilayer Material

在金属目标表面涂敷吸波材料可以有效地抑制雷达散射截面,增强雷达目标的隐身性能,而在求解这种目标的雷达散射截面过程中一个重要的问题是计算介质表面的反射系数.给出了一种求解反射系数的通用公式,并且以金属平板为例分别计算其在涂敷三层和五层介质时的反射系数,以及有涂敷五层介质时金属球的雷达散射截面.

Coating material controls efficiently radar cross section （RCS） and increases the stealth capability for metal objects. It is important to calculate the reflection coefficients on the surface of the multilayer material for RCS. A current formulation for calculating the reflection coefficients is given. The reflection coefficients at the panel＇ s surface with three and five layers material and RCS of a conducting sphere with five layers material are calculated.
