  • Wu, T.K.; Farazian, K.; Golshan, N.; Divsalar, D.; Hinedi, S. (1993-06-16)
    The feasibility of using a low gain antenna (LGA) as a mobile terminal antenna for helicopters is described in this paper. The objectives are 1) to select the lowest cost antenna system which can be easily mounted on a ...
  • Olsen, E.; Levin, S.; Jones, D.; Gulkis, S. (1993-08-16)
    In support of the development of NASA's High Resolution Microwave Survey (HRMS) Sky Survey Operational System (SSOS), we have conducted exploratory observations at 1.4, 1.7, and 2.3 GHZ at DSS 13 (Venus Station) in Goldstone, ...
  • Wheeler, Kevin; Hensley, Scott; Lou, Yunling (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2004., 2004-04)
    We are proposing to develop a miniaturized polarimetric L-band synthetic aperture radar (SAR) for repeatpass differential interferometric measurements of deformation for rapidly deforming surfaces of geophysical interest ...

  • Moriarty-Schieven, G.; Anderson, B. G.; Wannier, P. (1997)
    L1457 is the closest known molecular cloud (65pc), and lies near the edge of the local hot bubble, and well out of the galactic plane (b~ -34 deg).
  • Wannier, P.; Keene, J.; Powers, J.; Butner, H.; Moriarty-Schieven, G. (2000-04-20)
    Young T Tauri stars in Taurus have been found to have a high incidence of multiplicity, with the fraction of close (<~100 A.U.) companions found to be 0.40 +/- 0.08(Ghez et al. 1993; Leinert et al. 1993; Simon et al. 1995; ...
  • Moriarty-Schieven, G.H.; Butner, H.M.; Wannier, P.G. (1995)
    Evidence is presented that L1551NE, a very young protostar in the Taurus molecular cloud complex, possesses an outflow, that the optical/infrared reflection nebula is associated with the blue shifted outflow lobe, and that ...
