Analysis of image motion of satellite remote sensing camera

With the development of aerospace remote sensing technology, the ground resolution of remote sensing camera enhances continuously. Since there is relative motion between camera and ground target when taking pictures, the target′ image recorded in recording media is moved and blurred. In order to enhance the imaging quality and resolution of the camera, the image motion had to be compensated for. Through establishment of the mathematical model for computing the remote sensing image motion, image motions due to various factors were quantitatively analyzed. It is shown that, when image motion of satellite camera is compensated for, which due to the random change of satellite altitude can be ignored, but those resulted from satellite moving along its orbit and the Earth rotation must be compensated for. Finally, through simulation verification of an example, an image motion compensation scheme with mechanical method for satellite remote sensing camera is work out.
