Access to satellite ground target area can be taken way to access the imaging time window

The present invention discloses a method for obtaining the target area on the ground satellite access time window can be captured image, comprising: preprocessing the target area on the ground, the computation time nadir track adjacent intervals, and the calculation period is divided; calculated first time period of satellite ground target area can take access time window for imaging; preliminary calculations all the time period of satellite ground target area can take access time window for imaging; for the time period satellites all preliminary calculations of ground targets region access time window can be taken to optimize the image, acquire accurate satellite time periods in all targets on the ground recordable region access time window for imaging. With the present invention, quick access to the target area on the ground remote sensing satellite access time window can be taken imaging, to improve the efficiency of the remote sensing satellite ground access time window of the imaging target region to improve sensing satellite imagery ability to respond quickly to emergencies.
