摘要 该文采用基于非均匀有理B样条曲面(NURBS)建模的物理光学方法结合矩量法(MoM-PO)分析任意形状电大散射体附近天线的受扰方向图。采用插值驻相点技术加快了方向图的计算速度。文章推导了基于有理贝齐尔曲面的物理光学散射场计算公式,采用驻相法(SPM)计算有理贝齐尔曲面上的物理光学感应电流积分从而得到物理光学散射场,并利用物理光学散射场迭代矩量法区域的电压矩阵。通过与传统平面片建模的物理光学方法的计算结果对比,说明该文方法的有效性和计算速度快的优点。 The hybrid iterative Method of Moments and Physical-Optics method of moments （MoM-PO） is used to analyze radiation pattern of antenna around an electrically large platform modeled with Non-Uniform Rational B-Spline （NURBS） surfaces. The formula of scatter field based on NURBS surface is deduced. Stationary Phase Method （SPM） is applied to the integral of induced current on the rational Bezier surface. The process of obtaining stationary point is accelerated by interpolation technique. Results obtained by this method and by MoM-PO based on triangle facet model agree well while the former is more efficient in execution time.
