Abstract
A tracking error covariance matrix updating unitthat updates a tracking error covariance matrix P(−) before update at a sampling time k by using a nominal distance difference error parameter σΔand that outputs the tracking error covariance matrix P(+) after update is disposed, and a TrackDOP calculating unitcalculates an evaluation index TrackDOP for tracking accuracy for a target by using both the tracking error covariance matrix P(+) after update, and the nominal observation error parameter σΔ.
