Research on the delay measurement of satellite antenna receiving link

摘要：

Research on the delay measurement method of satellite antenna receiving link, design the test methods by the identical frequency system and the variable frequency system, innovatively use four-port network analyzer and the pulse modulation method to measure the delay of variable frequency system. Simultaneously use the network analyzer transfer coefficient and the time interval counter with the identical frequency system. Then choose X band satellite antenna to qualify the result. Furthermore measure the delay segmentally, which the whole system can be divided into three parts according to the signal transmission. Lastly fulfill the whole link measurement of Nanosecond delay. The paper provide the data-correctional of delay model in accurately orbit control, deep-space exploration and other major scientific test tasks and so on, at the same time put forward new ideas about delay measurement of the variable frequency system, which have high practicability and generalization.
