Research on Technique of VLBI Data Correlation Post Processing in Deep Space Navigation

摘要：

　　Correlation post handling includes accomplishing error corrections and outputting delay and delay rate in VLBI data processing.For multicenter VLBI observation data, there is interchannel delay which should be calibrated with quasar phase, which is phase calibration.Correlation post handling makes bandwidth synthesis to phase after calibration and gets high precision delay consequently.We focus on interchannel data in data processing of ChangE-3 Project, adopt difference methods to make correlation post handling and simulating analysis.The results show correctness and validity of method which is put forward in this paper.
