Multipath VLF propagation effects on correlation receivers( Book )

3 editions published in 1981 in English and held by 56 WorldCat member libraries worldwide

The effect of electromagnetic propagation at very low frequency in the earth ionosphere waveguide can distort wideband communication waveforms and produce a splitting of the correlation peak of the received signal at a model interference null where multipath signals arrive out of phase. Propagation from an inclined dipole antenna trailed behind an orbiting aircraft can cause split correlation pattern to fluctuate throughout the orbit period. For the case of an MSK (minimum-shift-keying) signal format, expressions and graphs are given for the correlation vector, as a function of receiver synchronization time and aircraft flight direction.

XUV aluminum spectra of laser-produced plasmas by G. A Doschek( Book )

3 editions published in 1980 in English and held by 53 WorldCat member libraries worldwide

XUV aluminum spectra from 200 to 500 A of laser-produced plasmas are discussed. The plasmas were obtained by focusing Nd:glass and CO2 laser pulses onto planar targets. The spectrograph was a normal incidence instrument without an entrance slit. Therefore monochromatic images of the plasma are formed at the focal plane, rather than spectral lines. Kodak 101 film was used to record the spectra. Images of the plasmas due to transitions in Al V through Al X were identified using a theoretical synthetic aluminum spectrum. The time- and space-integrated relative numbers of the ions form Al V through Al X can be obtained from a comparison of the synthetic and laser-plasma spectra. The comparison enables determination of the film calibration curve and the efficiency of the instrument with wavelength. The morphology of the expansion of the plasma is also discussed. The plasma of the highest temperature ions (Al X) expands outward in cylindrially shaped structures. The expansion of the lower temperature plasma (such as Al VII) is also cylindrical in appearance, but the images are not as tightly confined to the target normal as for the hotter ions. (Author)
Revised listing--S201 far-ultraviolet atlas of the Large Magellanic Cloud by Thornton Page( Book )

1 edition published in 1982 in English and held by 9 WorldCat member libraries worldwide

Far-ultraviolet electrographic images, covering the wavelength ranges 1050 to 1600 angstroms and 1230 to 1600 angstroms, were obtained of the Large Magellanic Cloud during the Apollo 16 mission with the NRL Far-Ultraviolet Camera/Spectrograph (Experiment S201). The images were analyzed as described in the 'S201 Far-Ultraviolet Atlas of the Large Magellanic Cloud' (NRL Report 8206), and the 'Revised S201 Catalog of Far-Ultraviolet Objects' (NRL Report 8487). The listing of far-UV objects in the LMC provided here is improved in quantitative accuracy and completeness compared to that originally provided in NRL Report 8206. These improvements include more accurate estimates of interstellar extinction corrections, comparisons with more sensitive ground-based H alpha emission measurements, and calibration of the S201 photometry by comparison with OAO-2 photometry of objects in common. The listing presents ultraviolet brightnesses, measured on one or more of four frames (two 1050 - 1600 angstroms and two 1250 - 1600 angstroms exposures), for 473 objects or gruopings of objects in the LMC. Also listed, where available, are H alpha brightnesses of associated nebulosities, and values of hydrogen index (defined as ratio of H alpha brightness to far-UV brightness, both corrected for interstellar extinction).

Spectra of Scorpius XR-1, Cygnus XR-1, and Cygnus XR-2 are derived for the 1.5-13 keV photon energy range from proportional counter measurements made on September 8, 1967. (Author)
A Spectral Atlas of the Sun between 1175 and 2100 Angstroms by Olav Kjeldseth Moe( Book )

1 edition published in 1976 in English and held by 1 WorldCat member library worldwide

This atlas provides solar spectra with high spectral resolution which will satisfy the needs of both solar physics and aeronomy for information on the solar spectrum in the wavelength range 1175 to 2100 Angstroms. The spectra may furthermore be useful for comparison with stellar UV spectra and with the red shifted spectra of quasars. Specific intensities as functions of wavelength are shown for two quiet regions between 1175 and 2100 Angstroms and for one active region between 1680 and 2100 Angstroms. The two quiet regions, located at heliocentric positions cos theta = 0.73 and cos theta = 0.32, represent a disk and a limb spectrum of the sun. The absolute intensities are determined with an accuracy of + or - 25% and the wavelength scale is accurate to 0.025 Angstroms. The sepctral resolution is 0.07 Angstroms. (Author)

Absence of short-term variability of CTA 102 by J. M Bologna( )

1 edition published in 1966 in English and held by 1 WorldCat member library worldwide

"Short-time variations in intensity of about 40 percent, with a period of the order of 100 days, have been reported for the quasistellar radio source CTA 102 at 32.5-centimeter wavelength. We have observed CTA 102 at 25.5-centimeter wavelength over a 67-day, period and have detected no significant variations of intensity."
Observations of the polarization characteristics of galactic H2O sources by J. M Bologna( Book )

1 edition published in 1975 in English and held by 1 WorldCat member library worldwide

"Twenty-four H2O sources associated with H II regions have been examined for circular and linear polarization. No circular polarization was found in any source. Approximately 25 percent have been found to show linear polarization in at least some features. The percent polarization in W75 S varied in the same sense as the intensity, while the position angle of the polarized radiation remained constant. This, together with the fact that 25 percent of the sources show linear polarization, indicates that the cross-relaxation rate of maser-level degenerate substrates via infrared line radiation is almost equal to the stimulated emission rate in many H2O sources."

The equatorial latitude of auroral activity during 1972-1977 by N. R Sheeley( )

1 edition published in 1980 in English and held by 0 WorldCat member libraries worldwide

The equatorial latitude of auroral activity has been derived from both electron and optical observations with the DMSP satellites. Essentially all of these observations have been used to produce a nearly continuous plot of invariant geomagnetic latitude versus time during the 5-year interval June 1972 - September 1977. This plot has two main characteristics: (1) a diurnal variation of approximately ±5° which is somehow associated with the precession of the Earth's magnetic dipole axis about the Earth's rotation axis and (2) an irregular variation of roughly 5-10° for intervals of one to several days associated with the occurrences of solar flares and coronal holes. With the help of a condensed, Bartels-type display of these measurements, we conclude that (1) modest auroral expansions (to [lambda] ~ °) occur during the main body of high-speed streams from coronal holes and (2) great expansions (to [lambda] < 55°) occur at the leading edge of a high-speed stream or at a flat-produced interplanetary shock
