In order to improve the posture estimation accuracy of small ship, a regularized particle filter based on multidimensional autoregressive model (MARM) is proposed in this paper. The small ship has the characteristics of nonlinear stochastic dynamical systems. Particle filter algorithm has been proposed to deal with nonlinear problems for many years. Although it is effective, two problems often arise:...
This paper proposes a new TDOA estimation based on phase-voting cross correlation and circular standard deviation. Based on phase delay and kernel function, the proposed method generates a probability density function (PDF) of TDOA for each frequency bin. TDOA estimate is determined by voting the PDFs generated for all frequency bins. Peak positions of the bin-wise PDFs for the target signal are concentrated...
