| Abstract: | Using Ka-band to transmit satellite data is an effective technology wa
y to increase available bandwidth of satellite data transmission, and wi
ll become the development direction of satellite data transmission. For the lack
of in-depth technical research on S/X/Ka-band ground receiving system at home
and abroad,this paper analyzes the key technology of S/X/Ka-band antenna feed
and servo system,and presents the main technical specification demand and techn
ical realization way. Research results can provide technical reference for syste
m design and development. |
