摘要：

Colorado State University (CSU) operates the CSU CHILL radar at Greeley, Colorado as a NSF national facility. The VCHILL (Virtual-CHILL) project is aimed at developing and implementing protocols for providing the raw radar data to researchers in real-time over the internet. The Next Generation Internet has features, which could be used to transfer raw digitized radar signals (DRS) generated by the radar. A network transfer application using TCP to transfer DRS was developed. This network transfer application has been successfully tested to provide throughput of 90 Mbps over a 100 Mbps link and 300 Mbps over gigabit link. A software digital signal-processing module was developed. A network transfer application with User Datagram protocol as the underlying protocol was also developed. The performance of the software digital signal processing unit and the 'Reliable-DRS' version of the application to transfer the data across the network meet the requirements in most areas.
