摘要
基于物理光学和等效电磁流法，本文讨论了飞行器座舱光学区电磁散射特性和雷达散射截面（ＲＣＳ）的计算方法。利用场量幅度和相位加权法，求解了座舱内部结构散射场。座舱外结构散射场通过座舱罩表面的数学拟合曲面和物理光学近似未获得。文中给出了一个（０．４×０．４）ｍ２无金属镀层的座舱风挡玻璃和带有薄金属镀层的风挡玻璃的ＲＣＳ结果，证明了此种低ＲＣＳ座舱罩的隐身性能。
Based on the physical optica approximation (P.O) and effective electromagnetical current (EMC) method this paper discussed the dectromagnetical scattering characteristic and radar cross-section (RCS) calculation in optical region for an aircraft cockpit. The structural scattering fields inside of the cockpit are obtained by using the amplitude and phase weighing. The outside structural scattering problem are solved by modeling canopy geometry in terms of surface fitting and P.O. approximation. A practical example of the RCS of a (0.4 ×0.4)m2 windscreen glass with and without thin metal layer has been given to verify the stealth feature of the low RCS canopy of the cockpit.
