| 摘 要： | 航空成像光谱仪得到的图像，其临边的辐射值与飞机正下方（天底点）的辐射值差别较大，此种现像称之为扫描图像的临边效应，它严重影响图像的质量，使图像的有效使用面积大为减少，还可能引起错误的判读，为了消除这种影响。本文提出一种物理意义明确，在实施过程中简单易行，而有效的方法，文中将详述航空飞行方式、数据及图像处理方法，而不涉及星载扫描图像的处理问题。

| Abstract: | The airborne imaging spectrometer image makes the difference between limb radiance and sub airplane point(nadir) radiance. This phenomenon was called the scanning image limb effect. The image distortion is derived from airborne scanner so that useful area of the image decreases, or even one makes an erroneous image interpretation. An available method of eliminating scanning image limb effect was presented in this paper. The aviation plan with relation to this method was simplified and easily. The realizable aviation pattern, related data and image processing technique was already discussed. The satellite scanning image data processing has not been involved in this paper. |
