Szegő Quadrature Kalman Filter for Oscillatory Systems

IEEE Access, 2020
Filtering problems with oscillatory system dynamics commonly appear in real-life. However, the existing Gaussian filters, like the unscented Kalman filter (UKF), cubature Kalman filter CKF, Gauss-Hermite filter (GHF) and cubature quadrature Kalman filter

The Square-Root Unscented and the Square-Root Cubature Kalman Filters on Manifolds

Sensors
Estimating the state of a system by fusing sensor data is a major prerequisite in many applications. When the state is time-variant, derivatives of the Kalman filter are a popular choice for solving that task.

Extended target tracking with mobility based on GPR-AUKF

Heliyon
Simultaneously estimating the kinematic state and extent of extended targets is a nonlinear and high-dimensional problem. While the extended Kalman filter (EKF) is widely employed to achieve this goal, it may not be sufficient for mobility targets.
