摘要
为了探求一个可行的评价迷彩服近红外伪装效果的方法,以绿色背景为例,测定了10种绿色植物在波长范围380 nm^1 200 nm的反射率并制得反射光谱;引入聚类分析的方法对测得的反射光谱数据进行分析,以不同植物作为变量,对波长进行系统聚类,得到光谱特征在不同类别波段上的分布;在不同波段上拟合曲线制定相应的光谱范围用来评价迷彩服的近红外伪装效果,并对2种迷彩服进行了评价。结果表明:本文的评价方法可以对迷彩服反射光谱符合绿色植被的程度进行有效而准确的评价,同时整个评价过程较为明确可行,为其他类型背景的迷彩服评价提供一个合理的参考。
In order to find a feasible method to evaluate the near-infrared camouflage effect of camouflage clothes,the reflectance of 10 green plants in the wavelength range of 380 nm to 1 200 nm was measured and the reflectance spectra were obtained with green background as an example.The wavelengths were clustered systematically to get the distribution of spectral characteristics in different kinds of bands,and the corresponding spectral ranges were drawn up to evaluate the near infrared camouflage effect of camouflage clothes,and two kinds of camouflage clothes were evaluated.The results show that the evaluation method can effectively and accurately evaluate the degree of the camouflage clothing reflectance spectrum in line with the green plants,and the whole evaluation process is more clear and feasible,providing a reasonable reference for the evaluation of camouflage clothing with other types of background.
