    Publication Year: 1966, Page(s):629 - 631

    The author is concerned with the lack of performance built into many of the instruments provided for today's underseas research: over 35 percent of the ??off-the-shelf?? equipment fails to operate as delivered, while 75 percent of the developmental hardware fails to meet specifications, and 50 percent of the delivered developmental equipment fails to work. These figures, in part, detail why our pr... View full abstract»

    Publication Year: 1966, Page(s):632 - 639
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2488 KB)

    SUSAN is a novel electronic Doppler navigation system which can be used with moving vehicles including aircraft, missiles, satellites, and ships. The system uses a technique of time delays and frequency multiplication to determine the rates of change of the Doppler frequency component present on a signal received from a moving vehicle. From this information the range and velocity of the vehicle ca... View full abstract»

    Cited by:  Papers (48)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2267 KB)

    All sampling representations of band-limited signals involve infinite sums. The truncation error associated with a given representation is defined as the difference between the signal and an approximating sum utilizing a finite number of terms. In this paper truncation error is expressed as a contour integral for Lagrange interpolation, general Hermite interpolation, the Shannon series (cardinal s... View full abstract»

    The confidence limits for the pointing error of a gimbaled sensor relative to an off-gimbal reference are derived in this paper. The various misalignment angles and errors that lead to discrepancies between the indicated and the actual pointing direction are discussed in detail. A mathematical model is developed from which the statistics of the pointing error are derived. The confidence limits are... View full abstract»

    This paper deals precisely with the effect of quantum or step size in an analog-to-digital converter on the quantization noise in the output of MTI (moving target indication) radar processors. The correlation between quantization errors on successive pulses is considered in the analysis and is shown to have a small quieting effect on the output quantization noise. View full abstract»

    The self-charging of radioactive ultrafine particles, which is temperature independent, has a number of applications. The use explored in this preliminary study indicates that the enhancement of more than an order of magnitude in MHD conductivity is possible, if nonequilibrium can be maintained. The creation of ion pairs, the relationship between equilibrium and nonequilibrium effects, and the gen... View full abstract»

    The theory, fabrication, and performance of Bi2Te3 alloy-based flat plate thermoelectric generator for near-earth orbits have been previously described.1 A power output of 3. 1 watts/ft2 to a matched load at a solar flux of 130 watts/ft2 and 30 watts/lb at the unit cell stage is achieved. This paper presents changes in process and manufacturing procedures suitable for a production rate of 25 unit ... View full abstract»

    The purpose of this paper is to investigate the signal distortion which results when long, series-fed arrays are used for communication. It is shown that under certain conditions the antenna array can be considered a linear filter, the response of which is a function of frequency as well as spatial coordinates. The distortion accompanying the transmission as measured by the least mean-square diffe... View full abstract»

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2973 KB)

    The problem of optimally processing data with unknown focus is investigated. Optimum data processors are found by the method of maximum likelihood under a variety of assumptions that apply to most of the situations arising in practice. The unknown focus may be either an unknown parameter or an unknown random variable; the signal may be of known form or a random function; it is further assumed that... View full abstract»

  • Automatic Impedance Matching in DC Circuits

    Publication Year: 1966, Page(s):38 - 42

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (594 KB)

    The subject of impedance matching is well known in engineering. Whenever a power source containing some finite resistance is expected to supply power to a load, maximum power is obtained when the resistance of the load is made equal to the resistance of the source. This problem becomes serious as the ratings of the power sources become larger. In space applications, thermoelectric generators and s... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1398 KB)

    This paper deals with the performance of pulse Doppler radar in the presence of random fading. The behavior of this radar is studied as a statistical problem to bring out the limiting bounds of the ambiguity diagram and the nature of variance with respect to the Doppler frequency. The performance of the radar insofar as the first sidelobe is concerned, is shown to be better in the presence of fadi... View full abstract»

    This paper describes the principle and the signal design of a proposed new FM radar system. In order to measure the surface characteristics of a small target at a long distance, or to discriminate among multiple targets, very accurate range or Doppler resolutions are necessary [1]. The proposed system satisfies the range resolution requirement by detecting the target with two different resolutions... View full abstract»

  • Adaptive Power Conditioning for Solar Cell Arrays

    Publication Year: 1966, Page(s):43 - 47
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (787 KB)

    This paper describes a technique for the design of power conditioning equipment which insures optimal power transfer from a solar cell array to its load. This new concept, called ??adaptive?? power conditioning, forces a solar cell to operate at its maximum power point, regardless of its environment, its impedances, or changes in the source volt-ampere characteristics. When I autodemands decrease,... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2826 KB)

    Uniform coherent pulse trains offer a practical solution to the problem of designing a radar signal possessing both high range and range-rate resolution. The Doppler sensitivity provides some rejection of off-Doppler (clutter) returns in the matched filter receiver. This paper considers the use of a processor in which members of the received pulse train are selectively weighted in amplitude and ph... View full abstract»

    To determine the potential of a spacecraft, an electric field meter is needed to measure the field at the surface and in the neighborhood of the craft. A search was made for field measuring methods which would not involve rapidly moving parts. Several of these methods are discussed along with some experimental work performed to determine their feasibility. The use of the Stark effect in the rotati... View full abstract»

    If impending failures in aerospace systems can be predicted deterministically during a test or checkout period, action can be taken to replace or repair the defective parts and a mission failure averted. This has the effect of increasing the mission reliability of the system. There are several methods of predicting specific failures especially adapted to electronic systems, but also applicable to ...
