This article illustrates the high quality of dual-polarized data available from the CSU-CHILL radar system after installation of the new 8.5 m Dual-offset antenna. Measurements of stratiform rainfall are used to highlight the characteristics of the antenna and radar.
This article describes the architectural changes introduced by the signal processor/radar controller, and how the CSU-CHILL radar is brought into the modern era through the VCHILL initiative. There are sections on the digital transmitter, digital receiver and signal processor architecture. Examples of the capabilities of the new system are also presented.
The in house designed digital receiver / signal processing systems used in the CSU-CHILL and Pawnee radars continued to be tested and refined during 2007. (They were initially fielded on both radars during the summer of 2006). CSU-CHILL operations were suspended in July 2007 to prepare the Greeley radar site for the installation of the new dual offset feed antenna.
