摘要： 该文将相似理论应用于有耗雷达目标散射截面的缩比测量,并按照因次分析方法导出了目标原型与模型间的缩比计算公式.根据这些公式,可以从不满足物理缩比条件的有耗模型的测量值准确推断目标原型的雷达散射截面.

Abstract: In this paper, the theory of similarity and dimensional analysis are used for the scaling measurements of EOS of lossy targets'. Scaling calculation formulas between the prototype and models have been derived. By means of these formulas, the EOS of the prototype can be inferred precisely from the measured values of models, even though they do not meet the condition of physical similarity.

Key words: lossy target, radar cross section, scaling calculation, theory of similarity, dimensional analysis
