The Differential Phase Pattern of the CSU CHILL Radar Antenna
. The ~easurement of the differential propagation phase and copolar correlation coefficient are affected by the d1fferent1al phase pattern of the antenna system when operating in an alternate horizontal and vertical transmitting scheme. Direct phase pattern measurements of a large dish such as that of the CSU CHILL is difficult because of the need to obtain phase reference. A simple technique i...
متن کاملA Description of the CSU–CHILL National Radar Facility
The subject of this paper is the Colorado State University–University of Chicago–Illinois State Water Survey (CSU–CHILL) National Radar Facility’s S-band polarimetric research radar. Key features of this system include polarization agility (provided by the dual-transmitter, dual-receiver design), a recently updated signal processor, and a low (234 dB, two way) integrated cross-polar ratio (ICPR...
متن کاملObservations of Quasi-Symmetric Echo Patterns in Clear Air with the CSU–CHILL Polarimetric Radar
On a few occasions during the summer and fall of 2002, and again in the fall of 2003, the Colorado State University (CSU)–University of Chicago–Illinois State Water Survey (CHILL) S-band polarimetric Doppler radar observed dumbbell-shaped radar echo patterns in precipitation-free air returns. Dumbbell shaped refers to two distinct and quasi-symmetrical regions of echo surrounding the radar. The...
