Normal-gamma nonlinear radar extended target tracking filter
摘要
Abstract
For the nonlinear extended target tracking with complex anomalous noise,a normal-gamma nonlinear radar extended target tracking filter is proposed in this paper.Firstly,the traditional extended object modeling method is opti-mized,and the motion state and the extended state are formulated explicitly and independently.Furthermore,when the measurement noise is a abnormal noise,auxiliary variables are introduced to represent the uncertainty of the measurement noise covariance,which is a gamma distribution.Additionally,considering the particularity of radar measurement,the original nonlinear measurement is augmented to reduce the problem of information loss during the measurement transfor-mation.Finally,simulation experiments of extended target and group target tracking are conducted,and the multi-feature joint estimation performance of extended target tracking is assessed using the Gauss-Wasserstein distance,which verifies the effectiveness and stability of the proposed algorithm.关键词
