首次介绍了复杂目标近场散射计算的可视化方法。采用非均匀有理B样条曲面（NURBS）精确构造任意形状散射体，结合几何体近场透视变换和Z－Buffer技术实现了基于Win－dows平台的近场散射计算。提出广义雷达散射截面的概念并给出了若干算例。该方法充分利用了计算机3D图形设备的几何运算能力，运算速度快，精度高，可扩展性好。
For the first time, the visualization method of complex target near-field scattering calculation is introduced. The non-uniform rational B-spline surface (NURBS) is used to construct arbitrary shape scatterers. The near-field scattering calculation based on the Win-dows platform is realized by combining the geometric near-field transformation and Z-Buffer technique. The concept of generalized radar cross section is proposed and some examples are given. This method makes full use of the geometric computing ability of the computer 3D graphics device, which has the advantages of high computing speed, high precision and good scalability.
