Quality and interpretability of airborne imaging spectrometer data generally are degraded by radiometricdistortions which are related to the larger viewing field of remote sensor. During the period of data acquisition

some parameters

such as path radiance

atmospheric attenuation and the sun-object-sensor geometry

continuously change with viewing angle

which causes a severe radiometric distortion on airborne imaging spectrometer data in scanning direction. Additionally

non-Lambertin reflection of ground objects and relief of terrain strongly complicate the radionetric distortion. It is impossible to do data processing and quantitative analysis if radiometric distortions of data are not corrected properly. In this paper

a new method based on image itself is developed to correct edge radiometric distortion of airborne imaging spectroneter data. Experimental results presented in the paper illustrate that the proposed method is more practical

effective and efficient for radiometric restoration of airborne imaging spectrometer data.
