← ScienceWhich outcome results when an unoptimized Kalman filter overestimates noise?
A)State estimate becomes overly sensitive✓
B)Filter gain matrix converges too quickly
C)Process noise covariance becomes negligible
D)Measurement residuals approach zero constantly
💡 Explanation
State estimates become overly sensitive because the Kalman filter places more weight on measurements than state transition models; therefore errors propagate more easily, rather than being damped quickly because the algorithm trusts unreliable recent measurement data.
