CSU-CHILL is spread across multiple sites, and comprises a number of weather radar systems, laboratory and workshop space.
Weather Radars
CSU-CHILL
![](/images/thumb/0/0b/CHILL_Radome.jpg/297px-CHILL_Radome.jpg)
CSU-CHILL S- and X-band is a dual-wavelength S- and X-band, dual polarization scanning radar system located at the CSU-CHILL main site. The S-band transmitter can be selected between dual 1 MW Klystron transmitters or solid-state 24 kW transmitters. The X-band transmitter is a 25 kW magnetron. The antenna is an 8.5m dual-offset (1° at S-band, 0.3° at X-band).
The radar in its current form is designed to provide very high purity polarimetric data thanks to its unique offset-feed antenna design. The dual-wavelength capability with S- and X-band simultaneous operation is unique in the research radar community. The radar offers high spatial resolution at X-band thanks to the combination of short wavelength and large aperture antenna.
The radar site is located at the CSU-CHILL main site in Greeley, CO.
CSU Sea-Pol
![](/images/thumb/2/22/Sea_pol_small.jpg/220px-Sea_pol_small.jpg)
The CSU Sea-Pol ship- and land-deployable radar measures dual-polarization data over a range in excess of 200 km. It is designed for operation aboard Global-class research ships operated by the US oceanographic community, and has also been successfully operated on land-based deployments. The radar operates at C-band (5.65 GHz) and has a 4.3m stabilized antenna system.
The radar features dynamic platform stabilization, allowing it to perform earth-relative scanning strategies even on a moving platform such as a ship on the open ocean. A state of the art RVP900 digital signal processor outputs dual-polarization moment data, and provides the IRIS radar user interface.
The radar is packaged into two sub-assemblies, the radar shelter and the antenna platform. The radar shelter is housed in a 20' ISO container for ease of transportation and mounting onto research ships. The antenna platform is designed to mate to the top of the radar shelter, and holds the antenna positioner, antenna and radome.
CSU Sea-Pol is a part of the National Science Foundation's Community Instruments and Facilities Program, and may be requested through that program. When not deployed in the field, the radar is based at the CSU-CHILL main site in Greeley CO.
CSU CHIVO
![](/images/thumb/1/1f/CHIVO_ardec.jpg/267px-CHIVO_ardec.jpg)
CSU-CHIVO is a C-band radar system with a 250 kW magnetron transmitter and a 4.5m (1° beamwidth) antenna. The antenna and radome are on top of a 6.5m (20 ft) steel tower to raise it above surrounding ground clutter. It is packaged in a containerized format for ease of transportation.
The radar is based on the Vaisala WRM200 commercial weather radar system. It is normally based at the ARDEC South radar site near Fort Collins, CO where it supports research scientists at Colorado State University. In 2019, it was used by the National Weather Service office in Boulder, CO as a gap-filler during an extended servicing of the NWS Denver NEXRAD (KFTG). The radar has been deployed several times in support of field campaigns as well.
SPLASH/SAIL
This is a pair of X-band containerized radars designed for rapid deployment to remote locations. They feature 25 kW magnetron transmitters, with 1.6m antennas (1.3° beamwidth).
Miami W-band
The Miami W-band radar is a vertically-pointing, containerized W-band cloud radar system, operated along with the NOAA Physical Science Laboratory. It has a 1.2 kW Extended Interaction Klystron (EIK) transmitter. It has a number of antenna options, including 0.9m (0.25° beamwidth).
PSL W-band
The PSL W-band radar is a vertically-pointing, containerized W-band cloud radar system, operated along with the NOAA Physical Science Laboratory. It has a 1.2 kW Extended Interaction Klystron (EIK) transmitter. It has a 0.3m (1° beamwidth), and is designed for deployment on NOAA P3 research aircraft.
CSU/NASA D3R
CSU/NASA D3R is a dual-wavelength Ku- and Ka-band radar featuring solid-state transmitters and pulse compression receivers. It is trailer-mounted for ease of transportation. It is based at the NASA Wallops Flight Facility.
FrontX
FrontX is an X-band phased array radar system developed in partnership with FirstRF corp. It features a single-axis electronic scan antenna mounted to a mechanical positioner system, and is trailer-mounted. The combined transmitter power from the 64 T/R modules is 70W, and has a 2° beamwidth.
CSU Pawnee
CSU Pawnee S-band was a single-polarization S-band radar, and was decommissioned in 2015.
Locations
CSU-CHILL currently administers two permanent sites in Colorado
- CSU-CHILL main site, Greeley CO
- ARDEC South radar site, Fort Collins CO
Lab Facilities
In addition to the radar and remote sensing equipment, the CSU-CHILL facility also hosts an RF Instrument Lab, which is used by both CHILL staff as well as CSU students during construction and maintenance of the radar equipment.
Electronic Design and CAD Software
CSU-CHILL has licenses for several electronic design automation (EDA) and computer aided design (CAD) packages, including:
- Keysight Advanced Design System (ADS)
- Keysight Genesys
- Keysight SystemVue
- Altium Designer
- Solidworks
- Xilinx Vivado and ISE
In addition, students at CSU-CHILL have access to software offered by the CSU Electrical and Computer Engineering department.
