摘　　要：为了探索光谱成像干扰效果的评估方法,基于实施干扰前后光谱图像数据图像特性的变化,提出了应用实施干扰前后光谱图像熵的变化量评估光谱成像干扰效果的方法,结合光谱成像伪装干扰试验实测数据对该方法进行了验证分析。结果表明,图像熵的变化量可以定量、精确反映干扰对图像特性的影响,并可便捷、直观地展示光谱成像干扰效果在不同光谱波段之间的定量差别和细微变化,因此可以作为光谱成像干扰效果的一种定量评估指标。Based on the change of image characteristics of spectral image data after being jammed,a method for evaluating jamming effect on spectral imaging by using the change of spectral image entropy after being jammed is put forward,and verified by using the data of camouflage jamming tests with a kind of broad-band camouflage net and a hyperspectral imager.The results show that the change of image entropy can reflect the jamming effect on image characteristics quantitatively and accurately,and demonstrate the quantitative differences and tiny changes of the jamming effect between different spectral bands conveniently and visually.The change of image entropy could be used as a quantitative index for evaluating jamming effect on spectral imaging.
