The Kalman filter is one of the most influential algorithms of the 20th century, transforming how engineers and scientists handle noisy data. Invented by Rudolf E. Kálmán in 1960, this recursive algorithm processes a sequence of noisy measurements to produce an optimal estimate of an unknown variable's true state. From the Apollo missions to modern autonomous vehicles, GPS navigation, robotics, financial modeling, and even smartphone motion tracking, the Kalman filter is the backbone of sensor fusion and real-time estimation.
When you execute this script in MATLAB, you will see a plot where the red dots (raw sensor data) scatter erratically far above and below the true value line. The Kalman filter is one of the most
: Uses a deterministic sampling technique (sigma points) to pick sample points around the mean. It handles highly nonlinear systems much better than an EKF without requiring complex calculus derivations. From the Apollo missions to modern autonomous vehicles,
