19th conference on signal and data processing of small targets
作者: Nandakumaran, N. Sinha, A. Kirubarajan, T. McMaster Univ Dept Elect & Comp Engn ETF Lab Hamilton ON Canada
Radar systems have good radial resolution, but they have poor angular resolution that results in unresolved measurements. this problem can be mitigated by utilizing the spatial diversity of multistatic radar system. I... 详细信息

18th conference on signal and data processing of small targets
作者: Briers, Mark Doucet, Arnaud Maskell, Simon R. Horridge, Paul R. QinetiQ Ltd. (United Kingdom) Cambridge Univ. (United Kingdom) The Univ. of British Columbia (Canada)
the use of multiple scans of data to improve ones ability to improve target tracking performance is widespread in the tracking literature. In this paper, we introduce a novel application of a recent innovation in the ... 详细信息

作者: Sinav, A Balci, AM Bar-Shalom, Y Turkish Navy Res & Dev Ctr Command Istanbul Turkey
the effect of the crosscovariance in track-to-track fusion has been studied in [2] [3] [4] [5]. Ignoring the crosscovariance of the local track estimation errors leads to optimistic covariance for the fused state esti... 详细信息

20th conference on signal and data processing of small targets
作者: Kragel, Bret D. Danford, Scott Poore, Aubrey B. Numerica Corp Loveland CO USA
Bias estimation using objects with unknown data association requires concurrent estimation of both biases and optimal data association. this report derives maximum a posteriori (MAP) data association likelihood ratios... 详细信息

14th conference on signal and data processing of small targets
作者: Dunham, DT Hutchins, RG Independent Contractor (United States) Naval Postgraduate School (United States)
Since the early 1990s, significant research has been done on a relatively new algorithm called the Probabilistic MultiHypothesis Tracker (PMHT). the majority of this research has concluded that there are a few weaknes... 详细信息

18th conference on signal and data processing of small targets
作者: Drummond, Oliver E. Dana-Bashian, David CyberRnD Inc Culver City CA 90230 USA
Track fusion processing is complicated because the estimation errors of a local track and a fusion track for the same target are usually cross-correlated. If these errors are cross-correlated, that should be taken int... 详细信息
