Kalman Filter Tracking Algorithm

This text discusses the Kalman Filter tracking algorithm. The Kalman Filter is a linear estimation technique for state variables that models uncertainties as Gaussian distributions to handle the relationship between sensor measurements and predictions. Implementation of the Kalman Filter program requires proper definition and adjustment of key matrices: the state transition matrix (describing system dynamics), system noise covariance matrix (modeling process uncertainty), observation matrix (relating measurements to state variables), and measurement noise covariance matrix (representing sensor accuracy). Optimal performance is achieved through parameter tuning specific to the application problem. The algorithm follows a two-step recursive process: prediction (projecting state and covariance forward) and update (correcting estimates with new measurements). Consequently, the Kalman Filter tracking algorithm finds extensive applications across various fields including robotics, aerospace systems, natural sciences, and engineering domains where real-time state estimation is crucial.
