摘要
对于电大尺寸目标,利用目前的电磁散射特性数值计算方法来计算其RCS时,计算复杂度较高,无法有效地应用于优化设计。因此研究并构造了基于部分正交多项式的飞行器RCS计算代理模型。算例表明所构造的代理模型精度满足工程设计要求。
It is so difficult to calculate the RCS of electric large object by current numerical methods that the methods can’t be used to optimization designs effectively.Therefore,a surrogate model based on partial orthogonal polynomials was constructed to calculate the RCS in this paper.The result showed the surrogate model is precise enough for engineering.
