    This paper presents very briefly the nature and origin of the International Geophysical Year, and in more detail two areas of special interest: rocket studies of the upper atmosphere, and satellite studies. It brings out the scientific basis for the satellite program and the development of U. S. interest in launching a satellite for scientific observations. The present status of the program is com...

    Sometime during the coming geophysical year (July, 1957 to December, 1958) an attempt will be made to launch an artificial satellite in an orbit around the earth. The Office of Naval Research has been assigned the responsibility to perform this task and has established Project VANGUARD in the Naval Research Laboratory to carry it out. The Department of Defense turned to the Navy to manage this tri... View full abstract»

    The VANGUARD satellite launching vehicle is a three-stage rocket of which the first two stages are guided and the third stage is maintained in a fixed orientation while it is firing. The first stage, an improved Viking, serves primarily to raise the remaining stages to altitude. The second stage, another liquid-propellant rocket, contains the guidance for the three-stage vehicle and, in addition, ... View full abstract»

    The earth satellite vehicle telemetering requirements are briefly presented. Primary problems are propagation over extended ranges utilizing light weight transmitters, diversity of equipment needs during the testing phase, reliability, and complexity of operations. Some of the general considerations and planning are given. View full abstract»

    The next round of problems created by an earth satellite after it is placed in its orbit are those associated with proving that the satellite is in fact orbiting, and the measurement of its orbit. The magnitude of these problems for optical methods is discussed, and the Minitrack system developed by the Naval Research Laboratory for acquisition and tracking of the satellite by radio techniques is ...

    The tracking of artificial earth satellites is here viewed as an integrated research program. The physical and orbital specifications of the first U. S. satellites are assumed in the tracking program planned under an assignment made to the Smithsonian Astrophysical Observatory by the IGY Satellite Committee of the National Academy of Sciences. The optical program involves early acquisition trackin... View full abstract»

    Planning for the fullest possible scientific utilization of the initial group of U. S. satellites is proceeding actively under the supervision of the National Academy of Sciences and its appropriate Panels and Working Groups. An inert satellite, tracked from an array of ground stations, will provide a means of unprecedented precision for the determination of the geodetic figure of the earth, for t... View full abstract»

    The synthesis of a current sawtooth from a limited number of first harmonics has been studied. It was found that good linearity is easier to obtain than a fast retrace. Scan distortion may be held below 5 per cent over 80 per cent of scan, by adding only 4 harmonics in a "least square" proportion. Fast flyback, on the other hand, requires 8 harmonics to be usable for commercial television. Several... View full abstract»

    A docile amplifier is one that remains stable when connected to any passive network of a specified class. A simplified geometrical approach is used to derive the docility criteria for passive-end-loading, ideal-transformer feedback, bilateral passive feedback, and arbitrary passive feedback.

    The concept of "bandwidth" is commonly used as a measure of the range of frequencies over which a network has an approximately constant gain. In this note the notion of bandwidth is extended to networks with arbitrary transfer characteristics. Specifically, it is defined in terms of the maximum allowable variance of the output of a network (to within a multiplicative constant) from that of an "ide... View full abstract»

  • Measurement of Microwave Dielectric Constants and Tensor Permeabilities of Ferrite Spheres

    The Bethe-Schwinger cavity perturbation theory is applied to measurements of the microwave dielectric constants and tensor permeabilities of small spherical samples of ferrites. For the dielectric constant measurements, a cavity opened at a position of minimum transverse wall currents is used. A frequency-shift method is used for measuring the real part of the dielectric constant and a cavity-tran... View full abstract»

  • The Effect of AGC on Radar Tracking Noise

    Publication Year: 1956, Page(s):801 - 810

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1342 KB)

    Radar angle tracking noise, such as that due to angular and amplitude scintillation of the target echo, is increased by the response of the receiver agc (automatic gain control) to the low frequency components of the fading of the echo envelope. An increase in angle tracking noise spectral density by a factor of two to three is representative of what can happen when the radar echo envelope is appr... View full abstract»

  • Theory of Noisy Fourpoles

    The well-known theory of fourpoles only comprises passive fourpoles and active fourpoles with internal sources of sinusoidal currents or voltages of defined frequencies. This theory is now completed for fourpoles with internal noise sources. Simple equivalent circuits are derived for such networks. They consist of the original but noise-free fourpole cascaded with a preceding noise fourpole in whi... View full abstract»
