为了探索研究利用宽波段伪装对光谱成像设备实现有效干扰的可行性, 并定量、客观评估光谱成像伪装干扰效果, 利用一种超光谱成像仪和一种宽波段伪装网进行了光谱成像伪装干扰试验, 并利用平均绝对差分对光谱成像伪装干扰效果进行了定量分析和评估。结果表明, 宽波段伪装网在超光谱成像仪各谱段均有一定的伪装干扰效果, 伪装干扰效果的显著程度因伪装前的目标特性、伪装网层数以及谱段的不同而不同; 利用平均绝对差分准则可以将伪装干扰效果的显著程度定量化, 并排除了主观因素, 使对光谱成像伪装干扰效果的评估更加精确, 因此是一种适用于光谱成像干扰效果评估的定量、客观准则。

To investigate and evaluate the jamming effect of broad-band camouflage on spectral imaging devices, camouflage jamming tests were carried out with a hyperspectral imager and a kind of broad-band camouflage net. The camouflage jamming effect on the hyperspectral imager was analyzed and evaluated quantitatively by using the mean absolute difference. The results show that the broad-band camouflage net has certain jamming effect on the hyperspectral imager at all the spectral bands, and the markedness of camouflage jamming effect varies with the target characteristics before being camouflaged, camouflage net layers and the spectral band. By using the mean-absolute-difference rule, camouflage jamming effect on spectral imaging could be evaluated quantitatively and impersonally, which makes the evaluation results more accurate. So the mean-absolute-difference rule could be used as a quantitative and impersonal rule for evaluating the jamming effect on spectral imaging.
