| 摘 要： | 根据飞行器等含腔复杂军事目标 RCS计算的需要,改进了射线跟踪法,并针对不同高频算法的特点,将像素法、射线跟踪法和边缘等效电磁流法结合运用,不同类别散射中心采用不同的方法计算,然后将复数量叠加得出目标的RCS,并充分考虑算法的协调.结合算例对方法进行验证,并将结果与矩量法等精确算法计算得到的结果进行了对比验证;运用本文方法对美国暗星无人机RCS进行了计算和分析.

| Abstract: | Based on the needs of RCS calculation of complex targets with open cavities,such as aircrafts,a shooting and bouncing ray(SBR) method is improved.Aimed at characteristics of different high frequency methods,pixel method,shooting and bouncing ray(SBR) method and equivalent edge currents method are combined for different types of scattering centers.And the plural values are added to compute the whole RCS of the object and the coordination among the methods is well concerned.A synthetic method is presented bas... |
