    This paper describes SIM (Systems Interference Monitor) which was developed to demonstrate compliance of the man-rated Gemini launch vehicle to the interference control requirements of MIL-E-6051C. The SIM incorporates simultaneous monitoring and remote control of many widely separated test points from a central location. The system includes a self-verification capability, two-wire high-input impe... View full abstract»

    A technique is described for significantly reducing the effect of multipath interference on field strength measurements made in conventional shielded enclosures by hooding the receiving antenna. Field strength measurements in a shielded enclosure and corresponding measurements in the open field were made at frequencies from 1 to 7 Gc/s with and without an antenna hood. It was found that when the a... View full abstract»

  • Radiating Mechanisms in a Reflector Antenna System

    Publication Year: 1965, Page(s):368 - 374
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (852 KB)

    The radiating mechanisms of a reflector antenna system are discussed. Means of computing the various component fields are given, including aperture radiation, direct feed radiation, and diffracted radiation. An offset parabolic reflector antenna system fed with a corrugated horn is treated as an example. Means of reduction of the undesired components of radiation are suggested. View full abstract»

    For interference evaluation studies, the voltage or power spectrum of transmitting systems must be known. This paper evaluates the magnitude of the sideband power levels for linear FM carriers. Carriers of this type are encountered in FM-CW and FM pulsed radars. Analytical expressions are derived and spectral amplitudes are plotted which permit rapid evaluation of spurious sideband powers as a fun... View full abstract»

    Since the establishment of the method for the measurement of radiation from FM and TV receivers, by Subcommittee 12-A of the International Electrotechnical Commission (IEC), the problem of establishing the conversion factor between the IEC method and the IRE method has aroused great interest. Because of the irregular radiation patterns of the receivers, the conversion factor may be determined pref... View full abstract»

  • Statistical Properties of the Output of Receivers under Interference Conditions

    Publication Year: 1965, Page(s):395 - 407

    interference mechanisms in receivers frequently entail nonlinear phenomena which alter the information sidebands of unwanted signals admitted to the receiver. Methods are discussed for obtaining useful statistical properties of the output of double-sideband receivers in such cases, when the original unwanted signals are double-sideband modulated with "Gaussian process" information. The solution is... View full abstract»

    In the past few years, an efficient and effective interference program has become increasingly important in the design and development of most modern electronic systems. The difficulty of realistically anticipating the technical implications and ultimate cost of interference problems is well known. Furthermore, it is not always easy to find applicable information in the literature. A summary is pr... View full abstract»

  • Distribution and Frequency Dependence of Unintentionally Generated Man-Made VHF/UHF Noise in Metropolitan Areas. Part II-Theory

    The frequency and range dependence of unintentionally generated man-made VHF/UHF noise in metropolitan areas may be interpreted by assuming that it is composed of random impulses which have been attenuated by propagation over irregular terrain. Man-made noise power per cycle of bandwidth measured for the frequency interval 150 to 500 Mc/s is shown to possess decrements of -10.4 dB/decade change in... View full abstract»

    Electronic measurements should provide the biomedical investigator with a mathematical description of the system under study. Like the physical sciences, the life sciences are bothered with interference that clutters the desired data. Some biomedical signals and sources of information are presented; an electro-neurophysiology system is used to illustrate the interference problem and its solution i... View full abstract»

    The possible sources and effects of electric charge accumulation and dissipation on spacecraft are considered. Areas of insufficient and/or unreliable information are noted. It appears that a major source of charge buildup is the charging currents of the jet engines. Near the earth there may occur additional charging due to lightning, passage through the atmosphere and the particles contained ther... View full abstract»
