[0002] Satellite reconnaissance is a reconnaissance method for obtaining information on the Earth's surface through satellite remote sensing technology, which has the characteristics of wide range, high controllability, and convenience. However, when the reconnaissance target is a moving target, if the reconnaissance is carried out according to a fixed strategy, it is easy to miss the moving target and reduce the reconnaissance effect. Therefore, a dynamic reconnaissance method is needed to improve the reconnaissance effect.
