title: [A method for smear removal of push-broom imaging spectrometers].
abstract: Smear is an inherent problem of area CCD and there have been many researches on how to deduct it. However, the imaging model of push-broom imaging spectrometer is very special, in which the usual methods are no longer applicable. To develop a new method that is suitable for the application of imaging spectrometer, a more detailed model was built. The problem of distortion of usual method was also analyzed and simulated. The original image of each channel was used to estimate the spectral distribution of the target, by which the contribution of smear of the black optical channel to each channel is quantified. Both simulation and restoration result of the remote sensing image showed that the new method worked well for the CCD smear deduction of push-broom imaging spectrometer.
