    Using the LOWTRAN 3 Midlatitude Summer Model which includes atmospheric effects, the reflected and emitted radiant flux densities from theoretical lambertian targets were calculated. The following conclusions were obtained. At 3.5 ¿¿m, q (ratio of radiant flux density emitted by a natural target to the radiant flux density reflected from it) is much less than one, except at high temperatures and e...

    The side-scan sonar method for study of the sea bottom enjoys widespread use at the present time. The interpretation of the records is restricted to those observers having some experience, and is offered in terms of geological and man-made features, bottom topography, and sediment types. The most subjective opinions are perhaps found in the latter category, and it is here that the attention of thi... View full abstract»

    An optimization theory for iron-cored induction-coil magnetometers in the audiofrequency range and above is described. The article shows, in a closed mathematical form, that for a given sensor weight a limited length of the ferromagnetic core and a chosen high-end cutoff frequency in combination with an available preamplifier there exists one particular magnetometer configuration, exhibiting minim...

    Spectral reflectance of snow under diffuse illumination is studied using the two-stream approximation of the radiative transfer equation. The scattering and absorption parameters of the radiative transfer equation-the single scattering albedo, the optical depth, and the integrated phase function are obtained from the grain size and density of snow. Analytical expressions for the intensity within t... View full abstract»

    Ground-based radiometric observations have proven to be effective means for remotely determining both the static and the dynamic thermal vertical structures of the lower troposphere. Since the meteorological parameters are random fields, the atmospheric radiance measured by a ground-based radiometer fluctuates randomly in time, and under suitable conditions, these fluctuations result essentially f...

    Radar backscatter measurements were made of shorefast sea ice near Point Barrow, AK, in May 1977, with a surface-based FM-CW scatterometer that swept from 1-2 GHz and from 8.5-17.5 GHz. The 1-2 GHz measurements showed that thick first-year and multiyear ice cannot be distinguished at 10-70° incidence angles, but that undeformed sea ice can be discriminated from pressure ridges and lake ice.

  • Lateral-Wave Propagation of Electromagnetic Waves in the Lithosphere

    The possibility of lateral-wave propagation of electromagnetic waves between horizontal electric dipoles near the floor of the ocean is reviewed. The general exact integrals for the radial electric field, which is the most useful component for lateral-wave transmission, are evaluated numerically for a range of possible conductivities of the lithospheric rock. Graphs and contour diagrams are shown ... View full abstract»

  • Shock-Identification-Computer on Board of the Spacecrafts HELIOS-1 and HELIOS-2

    One of the most important goals of the HELIOS-1 and -2 missions is the investigation of discontinuities with strong variations in the magnetic-field magnitude as, for example, shock waves. Observational studies of such events with high time resolution at low telemetry rates require an on-board automatic identification system and a big core memory. For this purpose a quality index is calculated on ... View full abstract»
