The Design of Network Transmission System Applied in Radio Astronomy Digital Equipment
Jiangying Gan · Annals of Shanghai Astronomical Observatory Chinese Academy of Sciences · 2012
When radio signal was processed by radio astronomy digital equipment,we need to transmit it to data record equipment,so that we can undertake further analysis and processing.In order to satisfy the requirement of data transmission,in this paper we designed a network transmission system based on Gigabit Ethernet.The test result showed that this system worked well when the data rate was lower than 640 Mb/s.Now this system has been applied in some radio astronomy equipments such as DBBC,continuous spectrum instrument and so on.
