| 摘 要： | 首先基于物理光学法对单个箔片的电磁散射特性进行了计算与分析，然后结合箔片姿态分布的统计规律，推导了圆形箔片平均雷达截面积（RCS）的精确公式，并利用数值积分的方法给出了方形箔片的平均RCS。在此基础上，分析了箔片平均RCS随频率的变化关系，结果表明，箔片的平均RCS近似反比于波长的一次方，且等面积的圆形箔片和方形箔片的平均RCS相差很小。最后，导出了箔片平均RCS的近似计算公式，推导了箔片云团RCS的统计特性，得到了箔片云团的RCS服从指数分布的结论。

| Abstract: | Characteristics of electromagnetic scattering by a single foil is studied and analyzed through physical optimal(PO) method.Based on the statistic distribution of foils' gesture,the formula of the round foil average RCS is derived and the square foil average RCS is gained by numerical integration.Based on the result,the relationship between foil average RCS and frequency is analyzed.It is validated that the average RCS of foil is approximately in inverse proportion to wave length and the average RCS differen... |
