Other AbstractA model for evaluation of the capability index of information acquisition in remote sensing was proposed. The main factors affecting the satellite remote sensing information acquisition ability, including orbit, imaging resolution, attitude maneuver ability were analyzed. By taking the comprehensive target identification as the standard, an evaluation model of ability index for the information acquisition which covers imaging resolution, target revisiting and attitude maneuver was established. The implementation process and the specific steps of the model were introduced. The model integrates two dimensions of target acquisition quantity and target acquisition precision, which could evaluate the practical physical significance comprehensively for remote sensing satellite information acquisition capability. With the Worldview series, Pleiades and a number of domestic and foreign optical remote sensing satellites as examples, the validity of the evaluation model was verified. The results show that the index model assess accurately the performance of different remote sensing satellites. It points out that the resolution of WorldView-3 is Less than twice as much as that of the WorldView-1, but its information acquisition capability is 3 times that of the WorldView-1.The resolution of Superview-1 is higher than that of the Pleiades, but its information acquisition capability is less than half of the latter. The validity of the evaluation model was verified, which demonstrates that evaluation model can provide a quantitative reference for the comprehensive evaluation of optical remote sensing satellites, and can provide a support for the evaluation of new optical remote sensing satellites. © 2017, Science Press.
