WebBriefly, a Kalman filter is a state-space model applicable to linear dynamic systems -- systems whose state is time-dependent and state variations are represented linearly. The model is used to estimate unknown states of a variable based on a series of past values. The procedure is two-fold: a prediction (estimate) is made by the filter of the ... WebMar 20, 2024 · 3.
