Abstract

The obvious vertical strip and chromatic aberration exist in the raw images obtained from the linear push-broom CCD, due to the different response among CCD detectors, the odd/even effect raised in signal transfer and the inconsistency of electronic link outside CCD array. In this paper, one relative radiometric correction method based on dark target image to calculate the bias coefficient and stable light target image to calculate the gain coefficient is discussed, taking the Beijing-1 small satellite panchromatic image as an example. This method is independent of the statistic characteristics of the corrected image, not only can remove the strip noise and the eliminate chromatic aberration, but also can make the color balance of the image, and is suitable for the relative radiometric calibration of linear push-broom CCD remote sensing image without calibration device onboard.
