    The paper deals with the design principles of a type of microprocessor-based receiver for the Decca Navigator continuous-wave, hyperbolic radio-navigation system. Two experimental receivers are described, one for automatic vehicle location, the other hand-portable. Both are fully automatic in operation. Novel features of their hardware software are outlined and the results of land-vehicle, marine,... View full abstract»

    Over the past decade or so, travelling-wave-tube amplifiers for communications have advanced from field replaceable glass bodies to packaged metal ceramic tube construction and from large, fully adjustable, linear power supplies to miniature, highly efficient, preset switched mode units. The principal features of modern tube design are based on metal ceramic technology, dispenser cathodes, two-sta... View full abstract»

    The GEC Hirst Research Centre was formally opened just over 60 years ago. This paper reviews the origins of the Laboratories, records their early history, and describes some of the technical work which they have undertaken. Although the Laboratories were set up to serve all the diverse activities of GEC, the present paper concentrates on electronics and communications. View full abstract»

    A recent paper1 has described the design and performance of a waveguide-fed parallel plate lens which provides five beams from a sixteen element antenna array, with sidelobes ¿ ¿ 20 dB and beam crossovers ¿ ¿ 10dB, in the frequency band 8¿12 GHz. A microstrip version of this lens has been designed, constructed and tested, with the addition of a beam port overlap network to now provide nine be... View full abstract»

    Radio waves can induce currents in electrical firing circuits used for blasting in quarries, and for similar industrial purposes, and could cause premature detonation if sufficiently strong. The paper describes an experimental and theoretical study of the currents in typical circuits, and a set of maximum-current curves is presented. These curves form the basis of a set of safe field-strength curv... View full abstract»

    The paper describes a technique for implementing moving target indication (m.t.i.) in an independent bistatic radar receiver. Conventional techniques for m.t.i., and the particular features and advantages of the bistatic radar configuration are also reviewed. The technique of phase priming by clutter echoes is suggested as a means for providing a coherent reference at the receiver, without need fo... View full abstract»
