    Ely, Todd A.; Chau, Alexandra H. (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2011., 2011-08-01)
    The traditional role that altimetry and velocimetry have played in spacecraft landings is to provide a direct measure of the spacecraft's surface altitude and surface relative velocity; however, their role in determining ...
  • Radar Ambiguities and Signal Processing Design Tradeoffs in the REASON Radar Sounder 
    West, R.; Gim, Y.; Tan, I; Hawkins, D. (Pasadena, CA: Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2017, 2017-05-08)
    NASA’s planned Europa Clipper mission would carry a radar sounder which operates at HF and VHF frequencies that can penetrate the icy shell of Europa. The sounder would be used to characterize subsurface bodies of liquid ...
  • Radar and libar radar DEM 
    Liskovich, Diana (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2011., 2011-07)
    Using radar and lidar data, the aim is to improve 3D rendering of terrain, including digital elevation models (DEM) and estimates of vegetation height and biomass in a variety of forest types and terrains. The 3D mapping ...
  • Radar and Optical Observations of Asteroid 1998 KY26 
    Ostro, S.; Pravec, P.; Benner, L.; Hudson, R.; Sarounova, L.; Hicks, M.; Rabinowitz, D.; Scotti, J.; Tholen, D.; Wolf, M.; Jurgens, R.; Thomas, M.; Giorgini, J.; Chodas, P.; Yeomans, D.; Rose, R.; Frye, R.; Rosema, K.; Winkler, R.; Slade, M. (1999)
    Observations of near-Earth asteroid 1998 KY26 shortly after its discovery reveal a slightly elongated spheroid with a diameter of about 30 m, a composition analogous to carbonaceous chondritic meteorites, and a rotation ...

  • Radar Astronomy 
    Ostro, Steven J. (1994-03)
    The nature of a radar experiment varies dramatically from target to target. For example, one usually transmits continuously for a duration equal to the two-way light travel time to the target (that is, until the first ...
