| Abstract: |
| In deep space TT&C system, due to its large antenna,how
to calibrate the phase difference between the sum channel and the
difference channel will be a key technology in towerless condition in the angle
tracking system. In order
to solve this problem with radio star,a design scheme is proposed through analy
sis.According to the features of radio star signal,theoretical analysis is made
and experimental result is provided.The feasibility of calibration with radio st
ar is verified, which has instructive meaning for the application of deep space
TT&C system. |
| Key words: deep space TT&C system angle tracking radio star towerless phase calibration |
