    The paper is devoted to the problem of estimating the angular position of targets detected by using the sequential-probability ratio test. An estimation algorithm, which uses the final value of the cumulative variable of the detection test, has been analysed by assuming a scanning step equal to one half the ¿¿3 dB antenna mainbeam aperture. The estimation algorithm is carried out by a decision-dir... View full abstract»

    Sequential techniques for signal detection are becoming increasingly important in radar applications. In the paper the authors focus their attention on the sequential probability ratio test (SPRT), used for radar target detection. This test was proposed and analysed for the first time by Wald, who developed a method to approximately determine the performance of the SPRT. Unfortunately, this method... View full abstract»

  • Depth-of-field improvements and removal of distortion in long wavelength imaging systems

    Publication Year: 1985, Page(s):149 - 152
    Cited by:  Papers (5)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (504 KB)

    A new approach to the problem of depth-of-field limitations and distortion in long wavelength imaging systems is proposed. The method exploits the backward propagation imaging algorithm and can be utilised in circumstances where data are recorded in the close near-field region. The fundamental theory of the technique is provided, and images from both simulations and experiment are presented as exa... View full abstract»

  • Wideband echo suppression using an improved bilateral opto-isolator circuit

    Publication Year: 1985, Page(s):153 - 158
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (605 KB)

    In the telephone network, an echo is generated at the hybrid junction that connects four-to two-wire lines. A conventional echo suppressor or canceller is designed on the assumption that the echo is actually induced. In contrast, in our method, using a bilateral opto-isolator circuit, the echo is suppressed at its origin. This bilateral opto-isolator circuit has not only the property of bilateral ...

  • Performance evaluation of the modified FBLP method for angle of arrival estimation using real radar multipath data

    Publication Year: 1985, Page(s):159 - 174
    Cited by:  Papers (9)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1271 KB)

    The paper presents the results of a detailed evaluation of the modified forward-backward linear prediction (FBLP) method used for angle of arrival estimation in a low-angle tracking radar environment. The results are based on real radar data pertaining to an angular separation of less than one standard beamwidth between the direct and image components impinging on the radar antenna. The results co... View full abstract»

  • Performance of SQAM systems in a nonlinearly amplified multichannel interference environment

    Publication Year: 1985, Page(s):175 - 180
    Cited by:  Papers (6)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (626 KB)

    The performance of superposed quadrature amplitude modulation (SQAM) systems, in a nonlinearly-amplified multichannel environment, in the presence of additive white Gaussian noise (AWGN), intersymbol interference (ISI), adjacent-channel interference (ACI) and cochannel interference (CCI), is investigated. This study is an extension of our previous work which was restricted to the performance study... View full abstract»

  • Timed gradient adaptive lattice equaliser

    Publication Year: 1985, Page(s):181 - 186
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (787 KB)

    The paper address the design of timed stochastic gradient-search adaptive lattice filters for applications in channel equalisation. Timing the lattice, i.e. freezing the PARCOR recursion, has previously been shown to offer a significant reduction in the algorithm noise of gradient adaptive lattice filters. Here we further simulate the effects of freezing the recursion, and show the point at which ... View full abstract»

  • Resolution of binary signals for threshold detection in narrowband non-Gaussian noise

    Publication Year: 1985, Page(s):187 - 192

    The resolution of binary signals in Middleton's class A narrowband non-Gaussian noise for both coherent and incoherent threshold or weak-signal detection is treated. A specific relative crosscorrelation coefficient p is defined for narrowband binary signals, and it is then shown that: (i) for coherent detection, `antipodal¿¿ (p = ¿¿1) signals are best, i.e. they give the smallest error probability...

  • Modelling of packet-switching networks with nodal blocking

    Publication Year: 1985, Page(s):193 - 197
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (493 KB)

    A packet-switching network with both end-to-end and local flow-control mechanisms is considered. End-to-end control is accomplished by window flow control and local control by using buffer management schemes between the input and transit traffic at the nodes. A queueing model of a semiclosed network is developed, which includes blocking models for the flow-control mechanisms and still retains a pr... View full abstract»
