Research on Predetection Data Processing Algorithm in MultipleTargets TT&C System

The Predetection data processing algorithm in the multiple targets TT&C(Telemetry,Tracking & Command)System with its design are introduced.The scheme of multi-point detection is proposed to improve the acquisition reliability.The bandwidth varying technique is adopted to solve the question of the tracking of high dynamics pseudo random code.The costas-AFC(Automatic Frequency Control)loop is adopted during the process of carrier tracking,so as to insure the tracking of high dynamics signal as well as to satisfy the requirement of measure precision.The data inversion technique is applied to improve the data efficiency as well as to insure the integrity of data.finally,several methods that could be used to improve the measure precision are summariged.It is proved by practice that these methods are effective and feasible.
