| Popis: | The purpose of relative radiometric calibration is to eliminate the strip phenomenon on the image. A new method with all detectors viewing the same scene is carried out. This paper provides the modeling and computation of satellite Yaw Angular Velocity(YAV) based on all the CCD detectors imaging the same region. The space coordinate transform process from object point on the earth to image point in the focal plane is found. Furthermore, the calculation method and process of YAV for satellite CCD camera imaging the same scene is given. Computation results indicate that the ground trajectory interval width is less than one pixel near the equator, and about four pixels below 35 degrees during calibration process more than 30 seconds imaging for 30000 detectors imaging the same scene. |
