摘要 文章实现了一种使用物理光学(PO)计算雷达散射截面的算法。目标模型用非均匀有理B样条(NURBS)曲面建立,并使用等参数等弦长方法剖分为N个四边形面元。在剖分面元上,使用Gordon方法将物理光学积分转化为闭合区域线积分。整个算法在保持计算精度的前提下有较高的计算速度。 A physical optics solution (PO) is presented for radar cross section (RCS) calculation. The object is modeled with NURBS (Non-Uniform Rational B-Spline) surface and be subdivided in equal string parameter method. The PO integral is solved by Gordon method. The whole algorithm is efficient in subdividing, shadowing and computing with an acceptable accuracy.
