摘　　要：应用物理光学和等效电磁流等方法对有源隐身中被保护目标的 RCS进行了计算 ,给出了某飞机模型 RCS的理论计算值和平滑值。并采用数理统计的方法计算了有源隐身目标散射场和对消场差值的均值和均方差 ,在方位角分别以均匀和随机规律变化时 。Based on the theory of physical optics and equivalent current method, the RCS of targets protected by active stealth is calculated. The values of the RCS of an airplane model are given by theoretical calculation and smoothness method. The mean and the mean square error of the difference between scattering field and cancellation field of the active stealth targets are calculated by means of mathematical statistics. The cancellation effect of scattering field is statistically analyzed, when the azimuth angle varies with the law of uniform and random distribution, respectively.
