    Notes: Mit Hilfe von Reagensgläsern aus Thüringer Glas, welche als Glaselektroden dienten, wurden unter Verwendung eines elektrostatischen Elektrometers als Nullinstrument eines Kompensationsgerätes Potentialmessungen an Natriumamalgamen gegen gesättigte NaCl-Lösung durchgeführt. Die Messungen erstreckten sich über einen Konzentrationsbereich von 0,6% bis 0,0005%.

    Kontinuierliche Herstellung und Verarbeitung von Diazoniumsalzen (1965)

    Notes: Bei der kontinuierlichen Diazotierung von primären aromatischen Aminen kann man oft auf eine Kühlung ganz verzichten, wenn man die Reaktionszeit bei Verwendung eines einfachen Rohrreaktors auf etwa 1 s verkürzt. Die Reaktionswärme wird dann von der Reaktionslösung unter Temperaturerhöhung auf 30 bis 100°C aufgenommen. In der Diazotierungsstufe werden sehr gute Ausbeuten erreicht. Auch die weiteren Umsetzungen der Diazoniumsalze laufen bei erhöhter Temperatur genügend rasch ab, so daß sich Zersetzungsprodukte nicht in störender Menge bilden. Nach diesem Verfahren wurden verschiedene Azofarbstoffe und aromatische Hydrazine in technisch befriedigender Weise hergestellt.

    Investigation of AIRSAR signatures of the Gulf Stream (1992)
    In:  CASI
    Details
    Publication Date: 2013-08-31
    Description: Extensive Airborne Synthetic Aperture Radar (AIRSAR) measurements were made on 20 July 1990 during the NRL Gulf Stream (GS) experiment which addressed a number of scientific questions relating to SAR imaging of the ocean surface in the presence of variable currents and the background thermohaline circulation. The nature of the electromagnetic (e.m.) backscatter from the North edge of the GS using polarimetric signatures and amplitude imagery from the AIRSAR data is addressed.

    An improved dual-frequency technique for the remote sensing of ocean currents and wave spectra (1984)
    In:  CASI
    Details
    Publication Date: 2016-06-07
    Description: A two frequency microwave radar technique for the remote sensing of directional ocean wave spectra and surface currents is investigated. This technique is conceptually attractive because its operational physical principle involves a spatial electromagnetic scattering resonance with a single, but selectable, long gravity wave. Multiplexing of signals having different spacing of the two transmitted frequencies allows measurements of the entire long wave ocean spectrum to be carried out. A new scatterometer is developed and experimentally tested which is capable of making measurements having much larger signal/background values than previously possible. This instrument couples the resonance technique with coherent, frequency agility radar capabilities. This scatterometer is presently configured for supporting a program of surface current measurements.

    Polarimetric Analysis of Scatterometer Data for Ocean Surface Wind Measurement (2004)
    In:  Other Sources
    Details
    Publication Date: 2019-07-13
    Description: An experiment using a polarimetric scatterometer (POLSCAT) has been conducted by JPL for ocean surface wind measurement. It shows that (sigma) (subscript)0 values for HH, W, HV, and VH have the property of even symmetry with respect to the upwind direction, and correlation coefficients between co- and cross-polarizations have the odd symmetry property. In this paper, the symmetry properties will be further examined using polarimetric analysis to investigate the depolarization effect, the scattering mechanism, and the polarization orientation angle. Theoretical results based on a two scale model are used to verify the derived experiment results. The newly derived symmetry property has the potential to solve the 180(deg) ambiguity in wind direction, and to enhance the accuracy of wind vector measurements.
