    The response of the Doppler radar speed meter was analyzed when there were two or more targets in a radar beam. When there are two targets of equal size and equal speed there is a fading condition and under a special condition, the radar becomes inoperative. When many targets with various speeds and sizes appear in a radar beam, the speed-meter output will fluctuate and the output represents eithe... View full abstract»

    In pomology, besides developing a high yield and good tasty fruit (such as the apple), the appearance or color of the fruit is very important for marketing purposes. This paper describes an integrating spectrophotometer that senses the incoming and shade energy of the electromagnetic spectrum continuously in the region between 3840 and 8960 Å at eleven different wavelengths. The energies of these... View full abstract»

    This paper is a survey of methods of high-impulse current and voltage measurement. Typically, such measurement techniques must now include capabilities for measuring high-energy impulses having peak powers as high as many megawatts, currents as high as many mega-amperes, or voltages as high as several megavolts, with rise times as short as a fraction of a microsecond (even as short as the subnanos...

    An experiment is described in which broad-band pseudo-noise modulation and tracking techniques were used to measure precisely the range from an earth station to near-synchronous satellites. Range measurements of approximately 22 000 miles were performed with a total error of less than 120 feet, with rms jitter errors of about 3 feet, and with readout resolution of 1 foot.

    The slowly moving arc has been instrumented for position and velocity. A practical arc model has been used that has particular application to the needs of industry. Analog circuitry has been developed that interfaces the arc plant with a digital computer. A computer strategy has been applied for time-average filtering without losing the resolution capability of the computer's A/D converter. Throug... View full abstract»

  • Admittance Bridge Determination of Quartz Vibrator Parameters Using Augmenting Immittance Elements

    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1762 KB)

    Bridge methods are the most accurate means of determining the parameters of quartz vibrators, particularly in the VHF region and above. Present and future crystal requirement specifications point to the increasing use of such methods to obtain the accuracy necessary for both filter and oscillator applications. A practical difficulty that arises is that the ranges of any given bridge are not compat... View full abstract»

    The optimal solution of perturbation signal waveform used to linearize the nonlinear transfer characteristic of the receptor array for an image sensing is sought through approximation. A completely linearized characteristic is obtained for the one-dimensional square-element receptor array without dead space by introducing this optimal perturbation signal to the system. Therefore, a zero sensing er... View full abstract»
