| 摘 要： | 本文提出用缩比模型计算电大目标雷达散射截面（RCS）的理论。通过复杂目标近远场电磁散射理论模型的分析得到，目标的雷达截面和目标的几何尺寸及工作波长有关系。当电尺寸相同时，目标雷达散射截面和其几何尺寸的平方成正比，缩比模型计算既适用于近场，也适用于远场。

| Abstract: | This paper introduces the method using the scaling model to compute and measure the RCS (radar cross section) of extremely large electric size target. It is concluded that the RCS of target is related to its geometry size and the wavelength of incidence wave. When its electric size is constant, its RCS is directly proportional to the square of the geometry size. The computing method using scaling model can be applied to both far field and near field. |
