In multi-detection (MD) systems including over-the-horizon radar (OTHR) systems, the forward-based receivers systems and passive coherent location systems, resolvable multiple detections of one target due to the multi-path propagation will be received, in which both identification (including measurement association and propagation mode/transmitting origin identification) and estimation (including...
This paper proposes a Gaussian sum filtering (GSF) framework for the state estimation of Markov jump non-linear systems. Through presenting the Gaussian sum approximations about the model-conditioned state posterior probability density functions, a general GSF framework in the minimum mean square error sense is derived. The minor Gaussian-set design is utilised to merge the Gaussian components at...
Overlapping ambiguity is a kind of ambiguity phenomena in the Chinese word segmentation. Up to now, the researches on overlapping ambiguity always focused on the 3-character overlapping ambiguity strings. In this paper the distribution and forms of overlapping ambiguity strings are discussed empirically. In order to deal with the overlapping ambiguity strings in different forms synchronously, a conditional...
Estimating the reliability and lifetime distribution of wireless sensor network is very useful in various applications. This problem is known to be NP-hard. In this paper, we present a hexagon tessellation sensor network model with role assignment scheme and estimate the reliability and lifetime distribution by employing a new improved Monte Carlo scheme which incorporates both simulation and analytic...
In this paper, a Hough transform (HT) based track initiation method is proposed to detect targets in 3L (low signal-to-clutter-ratio, low signal-to-noise-ratio, and low detection probability) environment using a new and effective accumulation method. In the new accumulation method, the contributions of each cell's votes are determined by the neighbors of the resolving cell, instead of just the cell...
