Info

What if the noise is NOT Gaussian? Given only the mean and standard deviation of noise, the Kalman filter is the best linear estimator. Non-linear estimators may be better. Why is Kalman Filtering so popular? • Good results in practice due to optimality and structure. • Convenient form for online real time processing. • Easy to formulate and implement given a basic understanding. • Measurement equations need not be inverted. 4
Word examples: • Determination of planet orbit parameters from limited earth observations. • Tracking targets - eg aircraft, missiles using RADAR. • Robot Localisation and Map building from range sensors/ beacons. Why use the word “Filter”? The process of finding the “best estimate” from noisy data amounts to “filtering out” the noise. However a Kalman filter also doesn’t just clean up the data measurements, but also projects these measurements onto the state estimate. 5
