Kalman Filter for Beginners: From Theory to MATLAB Examples (With Code Download)

Introduction: The Magic of "Noisy" Measurements

Imagine you are trying to track the position of a speeding car using a GPS. Your GPS device updates every second, but the reading is never perfect—it jumps around by a few meters due to atmospheric interference or urban canyons. If you rely solely on the GPS, your tracking line will look jagged and erratic.

1. Green Line: The perfect path.
2. Red Dots: The noisy, messy sensor data.
3. Blue Line: The Kalman Filter estimate. Notice how it smooths out the noise but eventually locks onto the true path!
