There are three signal channels in one camera  and twelve channels in three cameras for the three-line CCD camera. Because there is a little difference between different channels  the image grey of different camera channels is a little difference for the same region. Those differences include in two aspect: the difference between the cameras each other and the difference between different channels of the same camera. So they make a mistake when the images of different channels are matched. In the paper  the camera response curves have been described through ground radiation calibration to the multi-channel camera  furthermore  the channels calibration coefficients have been gotten based on making a certain the output basis channel. So the differences between different channels are reduced through radiation calibrating each channel  and the outputs of all channels are almost same  the accuracy of matching image is improved.
