    Carrier phase measurement is essential for high accuracy positioning in mobile Global Positioning System (GPS) applications. For GPS receiver design, a narrow loop noise bandwidth is desirable to reduce the phase jitter due to thermal noise. However, it deteriorates the capability of tracking loops and may result in cycle slips. Based on an adaptive bandwidth criterion, a new design procedure for ... View full abstract»

  • Distributed CA-CFAR and OS-CFAR detection using fuzzy spaces and fuzzy fusion rules

    Publication Year: 2004 , Page(s): 135 - 142

    The analysis of distributed CA-CFAR and OS-CFAR detection using fuzzy fusion rules in homogeneous and non-homogeneous backgrounds is presented. Each detector computes the value of the membership function to the false alarm space from the samples of the reference cells and transmits it to the fusion centre. These values are combined according to fuzzy fusion rules to produce a global membership fun... View full abstract»

  • Flight path strategies for 3-D scene reconstruction from bistatic SAR

    Publication Year: 2004 , Page(s): 149 - 157

    Proper design of receiver flight paths allows three-dimensional information to be encoded in sensed bistatic SAR phase history data. The authors show how the flight path taken by the receiving platform determines the resolution of nonparametric scene reconstructions and determines the variance of three-dimensional scattering centre location parameter estimates. Based on these relationships, a bist... View full abstract»

  • Wideband MVDR beamforming for acoustic vector sensor linear array

    Publication Year: 2004 , Page(s): 158 - 162
    Cited by:  Papers (17)

    A wideband minimum variance distortionless response (MVDR) beamforming approach for an acoustic vector sensor linear array is presented, which is based on coherent signal subspace preprocessing, to solve the problem of direction of arrival (DOA) estimation for wideband coherent acoustic sources. The concept of wideband focusing is introduced into wideband processing for the acoustic vector sensor ... View full abstract»

  • Displaced ping imaging autofocus for a multi-hydrophone SAS

    Publication Year: 2004 , Page(s): 163 - 170

    The problems caused by random sway errors in the tow-path of a single hydrophone, synthetic aperture sonar (SAS) are well known. If these horizontal displacement errors are left uncorrected and the tow-path is assumed to be straight, they have a devastating effect on the quality of the reconstructed image. Although on-board navigation instruments can help measure the gross departures from the stra... View full abstract»

  • Radar penetration imaging using ultra-wideband (UWB) random noise waveforms

    Publication Year: 2004 , Page(s): 143 - 148
    Cited by:  Papers (15)  |  Patents (3)

    Ultra-wideband (UWB) radar has been proven to be a very powerful tool for high-resolution penetration imaging of obscured objects. The authors discuss a radar penetration imaging technique using UWB random noise waveforms. The theoretical foundations for random noise radar, the random noise radar imaging model, and the synthetic aperture radar (SAR) image formation algorithm are presented. Typical...

  • Crame´r-Rao lower bound for tracking multiple targets

    Publication Year: 2004 , Page(s): 129 - 134
    Cited by:  Papers (8)

    The derivation and computation of the theoretical Crame´r-Rao lower bounds for multiple target tracking has traditionally been considered to be a notoriously difficult problem. The authors present a simple and exact solution based on the assumption that raw sensor data (before thresholding) are available. The multi-target tracking problem can then be formulated as recursive Bayesian track-be... View full abstract»
