    This paper describes the experiments at Evans Signal Laboratory which resulted in the obtaining of radio reflections from the moon, and reviews the considerations involved in such transmissions. The character of the moon as a radar target is considered in some detail, followed by development of formulas and curves which show the attenuation between transmitting and receiving antennas in a moon rad...

    This paper summarizes the results obtained from tests extending from 1943 to 1946 which were made to determine the meteorological factors controlling the propagation of centimeter waves. Oversea paths of 60 and 200 miles off the West Coast of Great Britain were used for the experiments. Continuous records of radio field strengths and frequent measurements of the meteorological conditions along the... View full abstract»

  • Ratio of Frequency Swing to Phase Swing in Phase- and Frequency-Modulation Systems Transmitting Speech

    Computed and measured data are presented bearing on the relation between the phase and the frequency swing in phase- and frequency-modulation systems when transmitting speech. The results were found to vary with different voices, with the microphone and circuit characteristics, and with the kind of volume regulation used. With a particular carbon microphone, it was found that a phase deviation of ... View full abstract»

  • The Helical Antenna

    The helix is a fundamental form of antenna of which loops and straight wires are limiting cases. When the helix is small compared to the wavelength, radiation is maximum normal to the helix axis. Depending on the helix geometry, the radiation may, in theory, be elliptically, plane, or circularly polarized. When the helix circumference is about 1 wavelength, radiation may be maximum in the directio... View full abstract»

  • Electronics of Ultra-High-Frequency Triodes

    The electronic behavior of ultra-high-frequency triodes is well understood, but there is need for an easily interpreted relationship correlating the various factors in terms of performance. An empirical relation for anode efficiency as a function of frequency, interelectrode spacing, and operating voltage which largely fulfills this need is deduced from the aforementioned theory and existing exper...
