| 摘 要： | 介绍了计算空腔内部高频电磁散射的射线跟踪法,推导了未进行简化处理的口径积分公式。与已有的计算结果相比,矩形截面直进气道的计算结果与参考值的吻合效果更好。从散射中心的观点出发,将像素法和射线跟踪法结合应用,给出了计算公式,通过软件实现了这些算法。给出了某无人机利用该算法得出的计算结果,并与实验值进行了比较分析。

| Abstract: | Shooting and bouncing rays(SBR) method is introduced to calculate the RCS of the cavity's inside structure and precise aperture integration formulae are understood. The calculated results of a strait inlet with rectangular section is better agreement with reference values than those of Hao Ling. Based on the point of scattering center, pixel method and SBR are combined to compute RCS of complex objects. Formulae are given and the method is realized by software. Then the calculated results of a pilotless aircraft are offered and compared with the experimental results. |
