The martian subsurface has been probed to kilometer depths by the Mars Advanced Radar for Subsurface and Ionospheric Sounding instrument aboard the Mars Express orbiter. Signals penetrate the polar layered deposits, probably imaging the base of the deposits. Data from the norther... |

Kobayashi, Satoru; Tanelli, Simone; Im, Eastwood, 2005, "Second-order multiple-scattering theory associated with backscattering enhancement for a millimeter wavelength weather radar with a finite beam width", https://hdl.handle.net/2014/39221, Radio Science, Vol. 40, RS6015, JPL Open Repository
Effects of multiple scattering on reflectivity are studied for millimeter wavelength weather radars. A time-independent vector theory, including up to second-order scattering, is derived for a single layer of hydrometeors of a uniform density and a uniform diameter. In this theor... |

Blacksberg, Jordana; Hoenk, Michael E.; Elliott, S. Tom; Holland, Stephen E.; Nikzad, Shouleh, 2005, "Enhanced quantum efficiency of high-purity silicon imaging detectors by ultralow temperature surface modification using Sb doping", https://hdl.handle.net/2014/39237, Applied Physics Letters 87, 254101, JPL Open Repository
A low temperature process for Sb doping of silicon has been developed as a backsurface treatment for high-purity n-type imaging detectors. Molecular beam epitaxy (MBE) is used to achieve very high dopant incorporation in a thin, surface-confined layer. The growth temperature is k... |

Duong, Vu A.; Stubbemd, Allen R., 2005, "Kurtosis approach nonlinear blind source seperation", https://hdl.handle.net/2014/41344, InTech '05, Phu Ket, Thailand, December 14-16, 2005., JPL Open Repository
In this paper, we introduce a new algorithm for blind source signal separation for post-nonlinear mixtures. The mixtures are assumed to be linearly mixed from unknown sources first and then distorted by memoryless nonlinear functions. The nonlinear functions are assumed to be smo... |

Anderson, John D.; Lau, Eunice L.; Giampieri, Giacomo, 2005, "Measurement of the PPN Parameter γ with radio signals from the Cassini Spacecraft at X- and Ka-Bands", https://hdl.handle.net/2014/39477, XXII Texas Symposium on Relativistic Astrophysics,Standford, California, December 13, 2005., JPL Open Repository
Radio Doppler data from the Cassini spacecraft during its solar conjunction in June 2002 can be used to measure the bending of light by solar gravitation. In terms of the standard post-Newtonian parameter γ, we find that γ - 1 = (-1.3 ± 5.2)x10^-5 in agreement with the theory of... |
