Research on target location algorithm for space-borne optical image system

This article uses satellite state vector and sensor's attitude angle to build a strict mathematical model for the relationship between the push-broom remote-sensing image coordinates and the terrestrial coordinates of sub-satellite point, based on the imaging mechanism of single linear array push-broom sensor. Furthermore, a certain area's image from domestic satellite is located by using this algorithm. The experiment proves the correctness of the conformation equation and shows that the algorithm can be used in the automatic ground target location and precise attack.
