Abstract: striping in the images which acquired by the linear array ccd blocks is mainly caused by disaccordance of each ccds . This problem can be solved by relative detector calibration. How to set up a fitted model of calibration depends on the satellite itself. Although physics model is reliable, it requires delicate equipments and some useful parameters are too complicated to find out. In practice, we always use signal or statistical models based on the image itself to deal with such problems. This article developed a new statistical model :the relative calibration model based on LMS linear regression. This model has been proved to be adaptable in dealing with lots of normal remote sensing images and get good results.

Key words: LMS, relative detector calibration, striping
