Square-Root Sigma-Point Information Filtering
The sigma-point information filters employ a number of deterministic sigma-points to calculate the mean and covariance of a random variable which undergoes a nonlinear transformation. These sigma-points can be generated by the unscented transform or Stirling's interpolation, which corresponds to the unscented information filter (UIF) and the central ...

Smoothing Filter With a Variation of Coefficients for Tracking a Maneuvering Aerodynamic Target
The article offers a new filter for tracking a maneuvering aerodynamic target. During the process of the filter synthesis, three main requirements were considered: the filter must provide a minimum smoothing error in the areas without maneuver; the ...

A Multipurpose Consider Covariance Analysis for Square-Root Information Filters [PDF]
A new form of consider covariance analysis suitable for application to square-root information lters with a wide variety of model errors is presented and demonstrated. A special system formulation is employed, and the analysis draws on the algorithms of square-root information ltering to provide generality and compactness.
