Summary: | The invention provides a yaw-guided low-orbit radar imaging satellite working parameter updating method and system, and the method comprises the steps: carrying out the coordinate conversion according to the instantaneous coordinate position of a satellite, and generating the six-element information of the imaging satellite corresponding to the instantaneous coordinate position of the satellite; when yaw guidance is not added, six-element information of the imaging satellite is processed to generate imaging satellite parameters; calculating six-element information of an imaging satellite to obtain an instantaneous satellite yaw guide numerical value according to the six-element information; updating imaging satellite parameters according to the instantaneous satellite yaw guide value; obtaining a difference value between the updated center moment and the initial orbit center moment, and judging whether the difference value is smaller than a preset moment threshold value or not according to the difference valu |
