    Phase modulation with an analytic signal, which is a Gaussian random process, is examined in order to determine the amount of spectrum conservation that may be achieved by using single-sideband phase modulation (SSB-PM) rather than conventional phase modulation (PM). The autocorrelation function is derived and found to be an analytic signal in terms of the autocorrelation function of the actual mo... View full abstract»

  • Two Statistical Cosite Signal-Prediction Models for Mobile Communication Systems

    Two statistical cosite signal-prediction models are developed taking into account the effect of mutual coupling between antennas on a finite conductive earth. Both models predict the expected values of the desired and interfering signals, their standard deviations and correlation coefficients at the input terminals of a communication receiver, when such a receiver is in the near field of a transmi...

  • The Conversion of Area Distributed, Incidental Radio Noise Envelope Distribution Functions by Radio Propagation Processes

    The central limit theorem may be invoked for man-made incidental radio noise to establish the limiting statistical distribution which is approached as either the noise source-to-observer distance or the observation frequency is increased. As these parameters separately increase, the distribution of the received noise-voltage envelope for either surface or airborne noise is shown to approach a Rayl... View full abstract»

    To help fill the need for environmental data essential to the design of reliable space-communications systems, a swept super-heterodyne radio-frequency interference receiver was developed for flight on the Lincoln Laboratory LES-5 and LES-6 experimental- communication satellites. The LES-6 receiver was adapted for use on an Air Force KC-135 aircraft. The receiver was designed to measure average po... View full abstract»

  • Radiation from a Dipole near a Conducting Cylinder of Finite Length

    Antennas radiating in free space or above a reflecting plane produce radiation patterns which are in general predictable. When these same antennas are mounted on bodies such as aircraft, submarines, or satellites, secondary currents may be induced on the fuselages and nearby conducting members. These secondary currents often result in unpredictable radiation in the forms of newly introduced polari... View full abstract»

  • Radiation Characteristics of Bent-Wire Antennas

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (797 KB)

    A mathematical model, which predicts the far-field power pattern of a wire antenna bent in one plane, is developed, and the classical approximation of a sinusoidal current distribution along the arc length is employed, neglecting all end and mutual coupling effects. General expressions for the complex Poynting vector, electric- and magnetic-field intensities are also derived in terms of the retard... View full abstract»

  • Investigation of a Dipole Model for Transient Analysis of Electromagnetic Field Coupling into Long Cables

    The authors describe a mathematical model for a long conductor exposed to a high-intensity transient electric field to aid in determining interface requirements at connected equipment. Dipole characteristics of the conductors are used to simulate the impedance and in turn to calculate the induced currents. Example calculations for four models, two conductor lengths, and two conductor sizes, are pr... View full abstract»

    The two-dimensional flux distribution in a magnetic shield of constant permeability and conductivity is presented in a series of magnetic vector-potential contour plots. The plots show the leakage-flux tubes in the shield and in the shielded region. Three- dimensionless parameters representing the shielding 1) thickness, 2) skin depth, and 3) permeability are introduced as the flux-distribution va... View full abstract»

  • Analysis of the Shielding Characteristics of Saturable Ferromagnetic Cable Shields

    A numerical technique is developed that may be used to analyze the shielding characteristics of a cable with a saturable ferromagnetic outer sheath in an intense low-frequency environment. The solution relates the center conductor current to the total current exciting a coaxial cable with a ferromagnetic sheath. Several examples are given to illustrate how saturation effects the shielding properti... View full abstract»

    Previously, a numerical solution was evolved that may be used to analyze the effect of material saturation on the low frequency shielding characteristics of a thin ferromagnetic cable shield. Numerical solutions are difficult to employ in design problems and so a simplified theory has also been developed. This supplemental theory, described here, yields simple equations useful in the design of fer... View full abstract»
