Research on Spacecraft Signal Combining for Antenna Array

Abstract:

An improved algorithm of spacecraft signal combining for antenna array and its implementation are researched. Firstly the composition of the antenna array experiment system and the processing flow of the signal combining are introduced. Then the high-precision delay extracting technique in signal combing processing is researched. Finally a signal combining experiment on the data-transmission signal of Chang’E-2 spacecraft is conducted and a full spectrum software combining processer is specially designed for the antenna array system. The experiment results show that the combining efficiency can reach 88.1%.
