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。
Aerial imaging spectrometer image, the radiation value of its edge and the aircraft just below (the sky-bottom point) the radiation value difference, this phenomenon is called the scanning image of the edge effect, which seriously affect the quality of the image, So that the effective use of the image area greatly reduced, but also may lead to wrong interpretation, in order to eliminate this effect. This paper presents a clear physical meaning, in the implementation process is simple and effective, and effective method, the article will detail the flight mode, data and image processing methods, and does not involve the processing of satellite image scanning.
