【摘要】 为了探索利用宽波段伪装对光谱成像设备实现干扰的有效性,并定量评估光谱成像干扰效果的方法。利用一种宽波段伪装网和超光谱成像仪进行了光谱成像伪装干扰试验,并利用相关函数对光谱成像伪装干扰效果进行了定量分析。结果表明,在试验条件下,实施伪装前后光谱图像之间的相关函数C值因伪装前的目标特性、伪装网层数以及谱段的不同,可在0.68到0.98之间变化,可以较灵敏、精确地反映伪装对光谱图像的影响程度,即干扰效果,并可便捷、直观地展示出干扰效果随光谱波段的变化情况。得到的评估结果符合通过目视谱图的直观判别结果,因此可以用于定量、客观地评估光谱成像干扰效果。更多还原

【Abstract】 To investigate the effectiveness of wider broad-band camouflage jamming on spectral imagers and to evaluate the jamming effect on spectral imaging quantitatively,camouflage jamming tests were carried out with a kind of broad-band camouflage net and a hyperspectral imager.Then,the camouflage jamming effect on the hyperspectral imager was analyzed quantitatively by using correlation function.The results show that,under the test condition,the correlation function between the spectral images before and after camouflaging varies between 0.68 and 0.98 with the target characteristics before being camouflaged,camouflage net layers and the spectral band,thus it can reflect the camouflage jamming effect on spectral images sensitively and accurately,and demonstrate the change of jamming effect with spectral bands conveniently.The evaluation results of jamming effect also accord with that obtained by observing spectral images.So the correlation function could be used to evaluate the jamming effect on spectral imaging quantitatively and impersonally.更多还原
