民用客机电磁散射特性的研究

Research of Electromagnetic Scattering Characteristic on Civil Airliner

利用数值方法对民用客机的电磁散射问题进行了研究,相比各种高频方法,应用矩量法(MOM:Moment Method)可以获得精确的数值结果。本文建立了一种幂级数形式的混合域基函数矩量法的通用公式,该混合基函数基于四边形剖分模型,对三维矢量有效地实现了降维处理,并可用来模拟民用客机的探测的散射特性。

The electromagnetic scattering from civil airliner is computed, and the results of the computation with the MoM are more accurate than those of the high frequency approximation. A new kind of general Hybrid domain basis function based on power series is presented in this paper, this basis function based on quadrangle modeling, and 3-D are reduced into 2-D efficiently, and such method is used to simulate the scattering characteristic of airplane.
