    Current developments in large-aperture antennas coupled with the projected performance of high-power electron beam and solid-state devices for generation and rectification purposes, make it possible to greatly extend present capabilities of microwave/millimeter-wave beaming systems. These include greatly enhanced radar performance as well as some totally new applications of energy beaming. These e... View full abstract»

    This paper describes the integration of an LMS adaptive array into a pseudonoise (PN) coded biphase modulated communication system. The paper explains how these systems my be combined and presents a systems overview of the interaction between the adaptive array and the signaling waveform. An experimental system is described, and typical performance results are presented. The hybrid system requires... View full abstract»

    The purpose of this paper is to introduce the reader to the elments of time-domain electromagnetics, which includes baseband-pulse technology and target-signature analysis. Baseband pulses are video or carrierless pulses of very short duration, whose spectral content is concentrated primarily from zero frequency through the microwave region of the spectrum. Work in baseband technology began more t... View full abstract»

    The development of a Nd : YAG space laser communication system is discussed with respect to history, potential applications, and present status. The basic design of an Air Force Space Communications Flight Test operable at a data rate of 1000 Mbit/s is described at both the system and component level. An engineering feasibility model of this system has been completed, and the results of tests data... View full abstract»

  • Grating-lobe suppression in phased arrays by subarray rotation

    A method of suppressing grating lobes in a uniform planar array is presented. In this method, the array is divided into equal sub-arrays which are physically rotated with respect to each other by specified angles. As a result, the grating lobes, which remain at the same angular distance from the main beam, are multiplied in number by the number of subarrays while their amplitude is divided by the ...

  • Effects of pulsewidth on Faraday tarotion

    Publication Year: 1978, Page(s):349 - 351
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (312 KB)

    We discuss effects of pulsewidth on the accuracy, of Faraday tarotion (spread-spectrum analog of Faraday rotation) as a measure of electron density. Results age presented for rectangular pulse envelopes of 10-100 cycles corresponding, for example, to 1-10 ns at 10 GHz. View full abstract»

    A generalization scheme of the active RC all-pass networks interconnecting one three-terminal network with another four-terminal one, constrained by a differential-input operational-amplifier, is presented. It is further shown that the scheme is, in fact, a completely general one for active filter realization. View full abstract»

  • Hilbert and Fourier transforms of polynomial ratio time signals

    Publication Year: 1978, Page(s):356 - 358
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (261 KB)

    Polynomial curve fittings have long been used to smooth data and provide functions from which, at specified times, samples may be obtained. Relationships of these polynomials to frequency content can be determined by including a denominator polynomial which does not essentially affect the fit over the data interval. Both Fourier and Hilbert transforms are found for general polynomial ratios, and t... View full abstract»
