Book A Conceptual Design Study for a Two Dimensional Electronically Scanned Thinned Array Radiometer

Download or read book A Conceptual Design Study for a Two Dimensional Electronically Scanned Thinned Array Radiometer written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-17 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: A conceptual design for the Two-Dimensional, Electronically Steered Thinned Array Radiometer (ESTAR) is described. This instrument is a synthetic aperture microwave radiometer that operates in the L-band frequency range for the measurement of soil moisture and ocean salinity. Two auxiliary instruments, an 8-12 micron, scanning infrared radiometer and a 0.4-1.0 micron, charge coupled device (CCD) video camera, are included to provided data for sea surface temperature measurements and spatial registration of targets respectively. The science requirements were defined by Goddard Space Flight Center. Instrument and the spacecraft configurations are described for missions using the Pegasus and Taurus launch vehicles. The analyses and design trades described include: estimations of size, mass and power, instrument viewing coverage, mechanical design trades, structural and thermal analyses, data and communications performance assessments, and cost estimation.

Book A Conceptual Thermal Design Study of an Electronically Scanned Thinned Array Radiometer

Download or read book A Conceptual Thermal Design Study of an Electronically Scanned Thinned Array Radiometer written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-08-09 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes conceptual thermal design study for an Electronically Scanned Thinned Array Radiometer (ESTAR). ESTAR is an instrument concept for the measurement of soil moisture from space using synthetic aperture radiometry. The thermal design goal is to minimize the orbital temperature variation of the radiometer receivers using established materials and techniques. Two design approaches have been investigated; the first uses the waveguide as a heat sink, and the second uses a nadir facing radiator on the receiver assembly. The second approach minimizes the receiver's impact on the waveguide temperatures. Predicted temperatures for all receivers are presented for the two cases indicating the transient thermal environments the receivers would experience during an orbit. In addition, the effects of the receiver heat dissipation on the waveguide temperatures are shown. Gould, D. C. Langley Research Center NASA-TM-110173, NAS 1.15:110173 RTOP 233-01-06-01...

Book Masters Theses in the Pure and Applied Sciences

Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 34 (thesis year 1989) a total of 13,377 theses titles from 26 Canadian and 184 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 34 reports theses submitted in 1989, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Microwave Radiometry and Remote Sensing Applications

Download or read book Microwave Radiometry and Remote Sensing Applications written by P. Pampaloni and published by VSP. This book was released on 1989-12 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains papers by well renowned scientists from all over world --- including Eastern Europe --- which were presented during a specialist meeting on microwave radiometry and its applications to remote sensing of the atmosphere and the surface of the earth held in Florence, Italy, in March 1988. The book is divided into five sections, some of which contain review papers which summarize the most recent advances in the field. The sections are: -- Microwave radiometry of the earth's surface -- Dielectric properties of natural materials -- Microwave radiometry of the atmosphere -- Synergism of passive and active microwave remote sensors -- Technology of passive microwave systems
