Visible Condition and Prediction of the Space Debris With Space-Based Phtotoelectricity

As activities for spaceflight increasing,more space dedris are generated,which make space environment worsened,and threaten the mortal spatial activities.The method with the space-based photoelectricity is more suitable than the one with the ground-based photoelectricity to observer the space debris.The space-based photoelectricity and the ground-based one is different in the visible condition.For the space-based photoelectrity,the optical visible condition of the space debris are under the condition of the sunlight,the earth shadow,the earth light,the earth background,the moonlight and so forth.The optical predicted method about the space-based photoelectricity is proposed,which can be used to predict and distinguish space debris.
