    Based on the fact that the performance of random error-correction decoding is insensitive to code symbols erased before its decoding process, a new approach to mitigate the effects of interference is derived. This approach consists of three basic functions: it modifies conventional interleaving, detects and deletes burst errors, and corrects random errors. Therefore this approach minimises the eff...

  • Airborne pulse-Doppler radar: false-alarm control

    Publication Year: 1987, Page(s):127 - 134
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1056 KB)

    Constant false-alarm rate (CFAR) techniques are compared in an airborne pulse-Doppler detection application. Standard methods such as CA-CFAR, GO-CFAR and OS-CFAR prove to be inadequate in dealing with the extreme variations of power between radar cells, resulting in large CFAR losses. Two new techniques, nadir-blanked CFAR and gradient CFAR, were specifically designed to accommodate these variati... View full abstract»

  • On the generalised Burg technique

    Publication Year: 1987, Page(s):135 - 140
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (657 KB)

    A new maximum-likelihood algorithm for Toeplitz covariance matrix estimation is introduced. The new algorithm requires substantially less computational cost than the generalised procedure proposed by Burg et al. It solves for the reflection coefficients rather than the covariance lags, and it calculates these coefficients successively starting from filter length one: the kth reflection coefficient...

  • Dyadic symmetry and Walsh matrices

    Publication Year: 1987, Page(s):141 - 145
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (547 KB)

    A unified matrix treatment which is defined for binary Walsh matrices is presented. This unified treatment, based on the concept of dyadic symmetry, defines Walsh matrices of different orderings using a simple equation. This equation in turn provides a straightforward derivation of various reordering schemes and Walsh matrix properties. Various fast computational algorithms can also be derived wit...

  • Simple computation of projection matrix for bearing estimations

    In the paper the idea of computing a projection matrix for bearing estimations by using any M rows of the covariance matrix, where M is the number of sources, is extended to the cases of low signal/noise ratio (SNR) and totally correlated sources. For low SNR, the projection matrix can be obtained by using off-diagonal terms of M rows of the covariance matrix, and a reduced search vector can be us... View full abstract»

  • Error rate performance of narrowband multilevel CPFSK signals

    Cited by:  Papers (8)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (808 KB)

    The paper presents a relatively simple method for analysing the effect of IF filtering on the performance of multilevel FM signals. Using this method, the error rate performance of narrowband FM signals is analysed for three different detection techniques, namely limiter-discriminator detection, differential detection and coherent detection followed by differential decoding. The symbol error proba... View full abstract»

  • Subspace approximation based covariance eigensystem solver

    The paper presents a subspace iteration based eigensystem solution algorithm for solving the minimum eigenpair (eigenvalue and associated eigenvector) of a Hermitian matrix. Specifically, the focus is on the class of covariance matrices which have near-Toeplitz structures. First, a modified Rayleigh quotient iteration (MRQI) method developed earlier is generalised to handle the near-Toeplitz struc... View full abstract»

  • Performance evaluation of convolutional codes with MPSK on Rician fading channels

    It is known that convolutional coding and Viterbi decoding together with high-level modulation can provide error-control protection without sacrificing bandwidth efficiency on additive white Gaussian noise (AWGN) channels. Bearing this in mind, the paper is concerned with the performance of short constraint length convolutional codes in conjunction with M-ary phase-shift-keyed modulation and maxim...

  • Theory of radar detection in coherent Weibull clutter

    Cited by:  Papers (9)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1847 KB)

    The paper deals with the problem of radar detection of a target echo embedded in Weibull clutter and white Gaussian noise (WGN). Relevant features of the paper, with respect to previous papers on the same subject, refer to the coherent nature of the Weibull process (that modelling the clutter) and of the processing chain. In more detail, the in-phase and quadrature components of the clutter echoes... View full abstract»

  • Characterisation of radar clutter as a spherically invariant random process

    Publication Year: 1987, Page(s):191 - 197

    A statistical characterisation of clutter as a complex random process is needed in the design of optimum detection schemes. The paper considers modelling complex clutter as a spherically invariant random process (SIRP), namely assuming that its PDFs can be expressed as non-negative definite quadratic forms, a generalisation of a Gaussian process. Relevant properties of SIRPs are summarised, and sh... View full abstract»

  • Correspondence: On a coherent model for log-normal clutter

    Cited by:  Papers (9)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (405 KB)

    The paper focuses on a recently proposed coherent model for non-Gaussian clutter, which achieves a log-normal amplitude and a nearly uniform phase by means of a nonlinear (exponential) transformation of a complex Gaussian process with suitable correlation properties. Along with the relevant features, few drawbacks of the model are put forth, concerning the lack of symmetry and the nonstationarity ... View full abstract»

  • Distributed radar detection theory. On the most powerful decentralised test

    Decentralised tests appear in the context of information processing from distributed sensors. A decentralised test is composed of peripheral tests and a fusion rule. While the peripheral tests yield decisions at the individual sensors, the fusion rule operates on the peripheral decisions to provide the final decision. To find a most powerful decentralised test, i.e. one with maximal probability of... View full abstract»
