| 摘 要： | 本文讨论了复杂飞行目标电磁散射分析及计算的一种方法，利用曲面拟合法的目标几何外形进行拟合，以样条函数拟合目标外形，并进行分元，利用物理光学近似技术求解每一分元的散射场，经相位综合，求得目标总射场，数学模型和实例证明了方法的正确性。文中讨论限于全金属导体目标的单站散射情况。

| Abstract: | A method of analysing and calculating the Radar Cross Section(RCS) for Complex aircraft targets is presented and verified.The method utilizes a computer program for modeling targets'geometry in terms of surface fitting.The actual exterior surface can be accurately modeled with spline function and divided into a lot of small surface elements. The scattering field calculation is based on the Physical Optics approximation for standard surface sheet.The total scartering field of the target can be obtained by using phase synthesis.The modeling procedure and some examples are given to verify the validrty of the method and presentation is limited to monostatic case for perfectly conduction targets. |
