Abstract:To improve the performance of the cubature kalman filter (CKF) in nonlinear non-Gaussian filtering system, the Gaussian sum cubature kalman filter (GSCKF) is proposed. A formulation of the CKF for the nonlinear system with non-Gaussian process noise and non-Gaussian measurement noise is presented. The GSCKF uses the Gaussian sum theory to divide the non-Gaussian system into several Gaussian sub-systems. And each subsystem is conducted the filtering process by the CKF. A target tracking problem with non-Gaussia… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
