    The paper describes an adaptive interacting multiple-model algorithm (AIMM) for use in manoeuvring target tracking. The algorithm does not need predefined models. A two-stage Kalman estimator is used to estimate the acceleration of the target. This acceleration value is then fed to the subfilters in an interacting multiple-model (IMM) algorithm, where the subfilters have different acceleration par... View full abstract»

  • Simultaneous frequency and direction estimation from parallel-array data

    A new method is proposed which provides the simultaneous estimation of both the centre frequency and the direction of arrival of multiple narrowband sources. Based on rotational-invariance techniques, the joint estimates are computed directly by appropriate processing of data from particular types of array instead of searching in a two-dimensional space. As a result, the computational efficiency i... View full abstract»

  • Partially adaptive array design using DOA estimation and null steering

    Publication Year: 1995, Page(s):1 - 5
    Cited by:  Papers (2)

    The authors propose a novel approach to designing a partially adaptive array using direction-of-arrival (DOA) estimation and a null steering technique. The DOAs of the interferences are estimated using some selected outputs of the signal blocking matrix to form the ensemble signal blocking correlation matrix. The eigenvector corresponding to the minimum eigenvalue of the ensemble signal blocking c... View full abstract»

  • Effect of noise on order parameter estimation for K-distributed clutter

    Publication Year: 1995, Page(s):33 - 40
    Cited by:  Papers (10)

    The paper addresses the characterisation of high resolution radar image textures in the presence of additive noise, which is inevitably present in the system. Two possible goals are analysed. In the first, the authors consider absolute texture description and identify the extent to which noise degrades performance by introducing a bias. The second is concerned only with segmenting the texture into... View full abstract»

  • Super-resolution range-Doppler imaging

    Publication Year: 1995, Page(s):25 - 32
    Cited by:  Papers (3)

    The general observation model for range-Doppler imaging is established from the point of view of multiple scatter-point localisation, and the optimum imaging procedure based on the maximum likelihood principle is given. Pursuing simplified procedures, the authors present three super-resolution range-Doppler imaging methods, including the linear prediction data extrapolation DFT (LPDEDFT), the dyna...

  • Detection performance of the trimmed-mean CFAR processor with noncoherent integration

    Publication Year: 1995, Page(s):18 - 24

    The ordered-statistic constant false alarm rate (OS-CFAR) detector has some advantages over the cell-averaging (CA) CFAR scheme, especially in cases where more than one target is present within the reference window or where this reference window is crossing clutter edges. The trimmed-mean (TM) CFAR processor is a more generalised OS-CFAR scheme which combines ordering and arithmetic averaging. The... View full abstract»
