    The current Geostationary Operational Environmental Satellites (GOES) are equipped to make cloud top measurements only. In contrast, a millimeter-wave radar allows 3-D measurements of precipitation associated with hurricanes ...
  • Yueh, Simon; Cline, Donald; Elder, Kelly (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2008., 2008-05-26)
    Preliminary analyses of the POLSCAT data acquired from the CLPX-II in winter 2006-2007 are described in this paper. The data showed the response of the Ku-band radar echoes to snowpack changes for various types of ...

    The Second Generation Airborne Precipitation Radar (APR-2) participated in the Genesis and Rapid Intensification Processes (GRIP) experiment in August and September of 2010, collecting a large volume of data in several ...
  • Ostro, Steven J.; West, Richard D.; Janssen, Michael A.; Lorenz, Ralph D.; Zebker, Howard A.; Black, Gregory J.; Lunine, Jonathan I.; Wye, Lauren C; Lopes, Rosaly M.; Wall, Stephen D.; Elachi, Charles; Roth, Laci; Hensley, Scott; Kelleher, Kathleen; Hamilton, Gary A.; Gim, Yonggyu; Anderson, Yanhua Z.; Boehmer, Rudy A; Johnson, William T.K. (Elsevier Science Inc., 2006-04-27)
    The Cassini mission includes 34 investigations of Saturn’s icy satellites by the 2.2-cm-wavelength (13.8-GHz) RADAR instrument, operating both as a scatterometric radar and a passive radiometer. These measurements are ...
  • Rush, John J.; Lichten, Stephen M.; Srinivasan, Jeffrey M.; Estabrook, Polly; Pollara, Fabrizio; Deutsch, Les; Preston, Robert; Hemmati, Hamid (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2011., 2011-01-24)
  • Im, Eastwood; Durden, Stephen L.; Tanelli, Simone (Chinese Institute of Electronics., 2006-10-16)
    The Cloud Profiling Radar (CPR), the primary science instrument of the CloudSat Mission, is a 94-GHz nadir-looking radar that measures the power backscattered by clouds as a function of distance from the radar. This ...
  • Im, Eastwood; Smith, Eric A.; Durden, Stephen L.; Tanelli, Simone; Huang, John; Rahmat-Samii, Yahya; Lou, Michael (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2003., 2003-11)
    A novel 35-GHz Doppler radar instrument concept and the associated critical technologies are being developed for detailed monitoring of hurricanes and severe storms from a geostationary orbit. This instrument is designed ...
  • Hodges, Richard E.; Zawadzki, Mark (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2004., 2004-06-20)
    We describe the design of a large dual-beam, dual polarized reflectarray designed for a space-based radar altimeter. This application requires a 2.16 X 0.35 m aperture that can be folded for launch stowage. Low mass and ...
