Web28 feb. 2024 · Illustration: Recall, the Kalman gain is given by. K t = P t − H t T ( H t P t − H t T + R t) − 1. where K t is the Kalman gain, P t − is the covariance matrix before the measurement, and H t is the measurement model, and the updated state estimate is given by. x t + = x t − + K t ( z t − H t x t −) WebA running average is one kind of Kalman filter. Following the notation in your first link X ^ k = K k Z k + ( 1 − K k) X ^ k − 1, a running average sets K k = 1 k. If your underlying model is that the parameter of interest doesn't change with time, it is what you get. Other forms are needed if X changes with time.
