摘　　要：准确度量目标与背景光谱曲线的相似程度对于目标伪装效果评价具有重要意义。基于灰色关联分析理论,定义了综合关联度量化光谱曲线间的相似程度;所建立的综合关联度整合了灰色关联度和一阶导数关联度的优点,全面反映了曲线之间的接近程度;综合关联度模型可以较为全面、客观地反映目标光谱曲线与参考光谱曲线的相似程度。研究结果可为目标伪装效果的客观评价提供重要量化依据。The accurate measurement of similarity between object spectral curve and referenced spectral curve is important to the evaluation of the camouflage effectiveness.The synthetic degree of incidence（SDI） was defined to measure the similarity of curves based on the grey relational analysis theory.It combined the advantages of degree of incidence and the first order derivative degree of incidence,which can comprehensively reflect the similarity between curves.The defined SDI can comprehensively and objectively measure the similarity between the object spectral curve and the referenced spectral curve.SDI can be the basis to measure the objective evaluation of the camouflage effectiveness.
