    A stochastic simulation Bayesian method for multitarget tracking is developed. This method uses a random sample in state space to represent the posterior state estimate distribution. The method is illustrated by simulations involving one target in dense clutter. Comparison with nearest-neighbours and probabilistic data association shows the superiority of the proposed method View full abstract»

  • Adaptive target tracking algorithms for airborne ultrasonic rangefinders

    The author proposes a method for adapting the sampling rate of digital filtering algorithms used for tracking targets moving relative to airborne ultrasonic pulse echo rangefinders. A method for the velocity dependent correction of estimated range is further introduced to compensate for the tracking errors arising as a consequence of the target sonar relative motion and the low speed of sound in a...

  • Adaptive instrumental variable method for robust direction-of-arrival estimation

    The authors consider the problem of estimating the directions of arrival (DOAs) of the signals impinging on an array of narrowband sensors with arbitrary geometry. By assuming that the noise covariance matrix has a block diagonal structure, an optimal spatial instrumental variable (OSIV) method is derived for DOA estimation. The OSIV method is computationally simple, yet it provides the minimum va... View full abstract»

  • Radar tomography for the generation of three-dimensional images

    Computer-aided tomography is normally a process by which a 2D cross-sectional image of an object is obtained by illuminating it from many different directions in a plane. For the case of radar imaging, microwave energy reflected by the object is processed to produce an image which maps the object's radar cross-section (RCS) density into the image plane. Each observation provides a 1D projection of... View full abstract»

  • General class of non-Gaussian coherent clutter models

    The author proposes a scheme to treat radar clutter as a non-Gaussian process. The approach is based on the concept of a fluctuating number of Gaussian scatterers. These scatterers can be of different types and may be grouped into classes on the basis of common statistical properties such as their covariance matrix and their number distribution functions (DFs). Using this idea, general expressions... View full abstract»

  • Digital signal processing of Decca Navigator radionavigation signals

    Publication Year: 1995, Page(s):71 - 80
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (688 KB)

    New techniques are described for digital signal processing of Decca Navigator radionavigation signals. A simulator (a computer program) is used to investigate the effects of different digital filter characteristics of the accuracy of phase measurements and to find an optimum filter bandwidth. The performance of the optimum filter in the presence of noise and other sources of error is investigated.... View full abstract»
