摘要: 本文对一种估算非金属翼面结构RCS值的工程算法进行了探讨。将非金属翼面结构的后向RCS看成是由若干个独立的散射源所组成的,用随机相位法对一种玻璃钢复材结构的翼面结构模型的RCS值进行了计算。

Abstract: In this paper, an engineering method is proposed for calculation of RCS for a nonmetallic wing structure model. The RCS of the wing structure model was described statistically on the basis of an equally likely relative phase relation between any two of the collection of simple scattering centers or components, of which the wing structure is made up.This calculation is the random phase estimate of RCS for the wing structure modelmade of glass fibre composites.
