In the satellite bidirectional time relative system which consists of time frequency

摘要

PROBLEM TO BE SOLVED: To provide a method for comparing temporal frequencies by a coherent carrier wave phase capable of high precision comparison.;SOLUTION: The method detects the topology of carrier wave signals, enhances measurement resolution when performing bidirectional temporal comparison by communication satellite relay, and easily solves multiple solutions generated by transmission delay measurement by using a main carrier wave and a sub-carrier wave signal neared by coherence therewith.;COPYRIGHT: (C)2008,JPO&INPIT
