Introduction: The Magic of Blending Noise into Clarity Imagine you are tracking a speeding car. Your GPS says it is at position 100 meters, but your radar says 110 meters. Which one do you believe? What if both are wrong because of bad weather or electronic interference?

The Kalman filter is optimal if your noise is Gaussian and your system is linear. For everything else—there’s the Extended Kalman Filter (coming soon in another tutorial).

| Parameter | What it means | If too high | If too low | | :--- | :--- | :--- | :--- | | (Measurement Noise) | Trust in sensor. High R = sensor is bad. | Filter ignores measurements (slow, drifts). | Filter trusts noisy spikes (jittery output). | | Q (Process Noise) | Trust in model. High Q = model is uncertain. | Filter jumps to every measurement (noisy). | Filter ignores real changes (lags behind truth). |
