The Tracking And Pointing Algorithm Of Target In Space Laser Communication System

Space laser communication is one of communication methods by usingoptical wave as carrier wave to transmit data. Currently, space lasercommunication has become a focus to which more and more people payattention.In space laser communication system, acquisition, pointing, tracking(APT) technology is quite important. Its pointing precision is a decisivefactor in the success of the whole communication system.This thesis describes the development of the APT system, includingforeign and domestic condition. It explains the structure and key technologyof the APT and studies the pointing and tracking algorithm of target in spacechannel condition. In the design of APT system, complex capstan device isused as console and Charge-couple Device(CCD) is used as a dector. Thisthesis studies the processing technology of the facular and some kinds ofalgorithms to track target. At last, it explains the hardware plat and softwarecontrol processing for realizing the algorithm.
