The mechanism of error composition of angle tracking in the presence of multipath reflection and diffusion from land or sea sruface is studied in this paper.The strategy of fusing multiple informations is proposed to implement synthetic smoothing for a TT&C (Tracking,Telemetry & Command)System.The principle,algorithm,and the implementation of the Synthetic Smoothing Algorithm are described.Finally,the test results of WYCK System in various sarface conditions of land and sea,especially the results of the mission test are presented.All the test results have shown that the Synthetic Smoothing Algorithm of tracking data is a effective approach to reduce multipath angle measurement error for autotracking systems.
