Characterization techniques of space objects based on point target information

Characterization of space objects creates a better understanding about the operational status and behavior of the RSO and point target detection is the main means to obtain information of space objects. While it is difficult to derivate the object characteristics from the product resulted from many unknown parameters, and amied to this problem, basic properties of the space objects were analyzed in this paper, then several advanced characterization methods were researched. The results show through proper algorithm design, much effective information could be mined from mesured data of point targets.
