Paper Abstract

Because of the problems existing in the optimal system and data transfer equipment on the payload, which cause the nonuniformity of the irradiation response on the panchromatic camera's CCD array of Beijing-1 of Disaster Monitoring Constellation(DMC+4, launched on 10th 2005), there are several radiometric response errors on images produced by the array pushbroom scanner. Such as odd and even stripe noise, the integrated lightness difference on the left and right part image, the lightness pulse at the centre of images and so on. The curve of the radiometric response of the panchromatic camera's CCD array on the uniform light irradiation has been measured in the laboratory. But some correlative parameters are still unknown and may be changed with the space environment. This article suggest new correction methods which are based on the array response model after filtering useless stripe noise of it by a special filter. Through the experiment of simulated images, the best method combination for de-striping and eliminating the PRNU (Photoresponse non-uniformity) phenomenon in the image simultaneously was found.
