    Several authors have suggested that hills, earth walls, excavated pits, or same other such obstacle might be used to shield ground-terminal antennas of satellite-to-ground communication links from radiated interference propagating at low angles (troposcatter, groundwave, etc.). As the tradeoff is between access or look angle and shielding efficiency, such pits would be most useful for synchronous ... View full abstract»

    The optimum frequency band for satellite communication systems is generally agreed to be between 1 and 10 Gc. Frequencies in this band are, however, already allocated and or assigned. One solution to this spectrum occupancy problem is frequency sharing, and one of the systems in this band with which a satellite system might have to coexist is the TD-2 microwave radio relay sstem (3.7-4.2 Gc). This... View full abstract»

  • An Empirical Estimate of the Contribution of Terrain Reflections to Interfering Signal Distributions

    Publication Year: 1965, Page(s):112 - 118
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2430 KB)

    This paper is a report on a problem which is thought to have rather general interest in the field of radar and communications systems. This is the problem of interference caused by the reflection of pulsed radar signals from the terrain in the transmitter-receiver environs. This problem has proved to be rather intractable to handle analytically and therefore the empirical approach presented in thi... View full abstract»

    The interference prediction model is a major tool in the effort to obtain electromagnetic compatibility in the crowded radio frequency spectrum. Work has progressed in the prediction modeling of the transmitter, antenna, propagation, and receiver, but additional expressions for the degrading effect of interference upon information output to the operator are required to complete the analysis. The p... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (5815 KB)

    Basic models for the synthesis of transmitter spectra for three different types of transmission have been presented. They are: (1) Amplitude modulation; (2) Conventional radar pulse; and (3) Pulse-compression radar pulse. Each one of the equations defining the models is suitable for pencil-and-slide-rule analysis. In general a great degree of precision is not required in EMI prediction. The graphs... View full abstract»

    Cited by:  Papers (12)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1058 KB)

    This paper presents a technique for establishing known, high intensity RF fields suitable for testing the susceptibility of electronic equipment to these fields. The technique overcomes a deficiency in tests for radiated susceptibility which are required by military specifications, such as MIL-I-26600. Such tests fail to use field intensities that are representative of the environments in which el... View full abstract»

    Envirornmental synthesis is defined as a procedure by which an electromagnetic enviromnent (including equipment types, numbers and deployments) is generated, based on partial information. There is a need for such syntheses since complete information in both current and future time periods will never be available. Another requirement arises when excessive computer time is a significant factor. Sinc... View full abstract»

    A 200-foot pneumatically operated, portable plastic tower has been constructed to permit measurement of radiated signals and also to permit the radiation of r-f signals for overall susceptibility measurements. The electronic package contained at the top of the tower is semiautomated and is controlled from a console on the ground. Cable losses have been eliminated by locating all r-f circuitry at t...

    This paper illustrates some fundamental instrumentation and measurment terms and the vague or midlesding manner in which they are frequently used. For example, the subject of accuracy is shown in four different common uses and interpretations. Misuse of the accuracy term is also illustrated in describing the performance of receiver linearity and dynamic range, the synthesis of recorder requirement... View full abstract»

    A technique for accurately measuring conducted radio frequency interference has been developed at the U.S. Naval Civil Engineering Laboratory. The technique involves the use of two current probes simultaneously to determine the impedance levels of the lines or equipment under measurement. The noise currents of the lines or electrical equipment are measured directly using one of the two probes. Kno... View full abstract»

    The Publications Conmittee wishes to correct an error made in the October 1964 issue of the Transactions (Vol EMC-6). In a paper by David T. Geiser, entitled "A method of DF error correction," Figure 3 was split and a part of it used as Figure 2. The correct form of Figure 2 is reproduced here. The Figure 2, as published, should be a part of Figure 3, as published. View full abstract»
