一种DOR侧音信号相关处理算法研究
Research on Correlation Algorithm of DOR Tones
摘要
Abstract
△DOR is a much more useful measurement for orbit determination than VLBI,which is widely used in deep space navigation.To enable the measurement,a spacecraft must emit several tones.The correlation algorithm of DOR tones is described.Firstly,the FX correlation algorithm is introduced,which is used to get differential phase.Then,the phase cycle ambiguity of DOR tones is defined and the method of resolution of phase ambiguity with a lower-frequency DOR tone is discussed.Finally,the simulation results show that the algorithm is correct.关键词
