    The fundamental concepts of sideways-looking radar are examined for both spatial processing with real apertures and temporal processing with synthetic apertures. The analogies between the different processing methods are identified in terms of the single target performance. Principal properties analysed are the resolution and signal/noise ratio. In addition, the effect of many scatterers is discus... View full abstract»

  • Time synchronisation of an HF radio modem

    Publication Year: 1982, Page(s):403 - 410

    In the serial transmission of a digital data signal over a voiceband channel involving an HF radio link, the impulse response of the channel may undergo large variations with time. When a near-maximum-likelihood detection process is used at the receiver, with no adaptive filtering of the received signal, the detector requires an estimate of the sampled impulse response of the channel, and this est...

  • Interrelationship between some statistical distributions used in radio-wave propagation

    Publication Year: 1982, Page(s):411 - 417
    Cited by:  Papers (3)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (627 KB)

    Several forms of statistical distributions are used in the study of radio-wave propagation. The paper refers to several of the commoner types, including the one-sided normal, exponential, Rayleigh, gamma, Nakagami-m and Weibull distributions, and shows that they are all simple interrelated forms of the Stacy distribution.

  • 30¿20 GHz domestic satellite communication system experiments

    Publication Year: 1982, Page(s):418 - 422
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (660 KB)

    Experiments have been carried out on a 30¿20 GHz domestic satellite communication system. This system employs both a fixed earth station having an 11.5 m-effective-aperture antenna and a small transportable earth station with a 2.7 m-aperture antenna. It was verified that a fixed earth station installed in a major-city telephone office can provide a transmission capacity of 480 two-way voice chan... View full abstract»

  • Bit synchronisation based on the sensitivity function

    Publication Year: 1982, Page(s):429 - 438
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1090 KB)

    In the paper a new bit synchronisation method based on sensitivity function analysis is suggested. The essential feature of the method is its applicability when no a priori information is available. The method is of adaptive form and involves the joint synchronisation and estimation of the binary interval. Special attention is devoted to jitter and noise influence analysis. An experimental model h... View full abstract»

  • Comparative adjacent-channel selectivity performance of phase-locked pilot-tone SSB mobile radio receivers with particular reference to the long-, short- and split-loop configurations

    Publication Year: 1982, Page(s):439 - 446
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (868 KB)

    There has been considerable interest, both in the USA and in the UK, in the use of 5 kHz pilot-tone single-sideband modulation for the VHF and UHF civil land mobile radio service. However, if single sideband (SSB) is going to be a commercially viable proposition, it will be necessary to use some form of automatic frequency control to reduce the specification and hence the cost of reference oscilla...

  • Phase control of pulsed broadband microwave amplifiers

    Publication Year: 1982, Page(s):447 - 451
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (517 KB)

    A phase shifter for pulsed broadband amplifiers is described. The phases of the input and output signals are compared in a polar discriminator, and an error signal is derived which steers a voltage-controlled phase shifter at the amplifier input. Applications are for smoothing out within-pulse and pulse-to-pulse phase shift in amplifiers and for providing a relatively accurate phase shifter for ac... View full abstract»

  • New topology for multiexchange digital networks

    Publication Year: 1982, Page(s):452 - 458
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (702 KB)

    The main features of a new topology based on the Cartesian product of complete graphs applied to multiexchange networks are presented. A method of modelling a multiexchange digital network at district level in a national hierarchical network using the new topology is given, together with the performance and cost analysis for a particular district. A comparison is then made with a least cost networ... View full abstract»

  • Simulation study of a signalling protocol for mobile radio systems

    Publication Year: 1982, Page(s):459 - 466
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (934 KB)

    An essential component of any trunked mobile radio system is the signalling protocol used for the purpose of call establishment. The paper presents computer simulation results of one such protocol designed for use with dedicated signalling channels and incorporated within the Advanced Mobile Phone Service. The latter is a high-accuracy cellular-structured mobile radio system currently being implem... View full abstract»

  • Operation of portable HF CDMA networks with controlled transmitter powers

    Publication Year: 1982, Page(s):467 - 474
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1193 KB)

    The use of networks consisting of portable HF radios multiplexed to a master station requires an effective supervision system. Spread-spectrum code-division multiple access provides flexibility in the number of users and has advantages over time and frequency multiple-access techniques for this type of network in that precise time or frequency co-ordination between the users is not needed. However... View full abstract»
