摘要
在金属飞机表面涂覆吸波材料可以有效地减小雷达散射截面(RCS),增强飞机的隐身性能。因此,精确的计算覆有介质涂层飞机的雷达散射截面非常重要。本文采用一种基于物理光学法来计算涂覆介质材料飞机的RCS。首先以涂覆两层介质的金属立方体为例将FEKO软件计算结果作为参照验证该算法的精度,然后以飞机模型为例,计算飞机的RCS和涂覆两层介质后的RCS,研究涂层对于飞机雷达散射截面的影响。
Coating aircraft controls efficiently radar cross section(RCS) and increases the stealth capability for aircraft.Therefore, it is great important to accurately calculate the RCS of coating aircraft.This paper deals with the problem of RC S of aircraft with coating using the method of Physical Optics.First, the paper lists a metal cube with two layers to validate the accuracy of its approach comparing with FEKO, and then calculate RCS of aircraft and the RCS of aircraft coated with two layers of medium coating.To study the influence of coating for aircraft RCS.
