Abstract :
In ibid, vol. AES-29, p.578-590 (Apr. 1993), J Sudano presented the optimal steady-state gains and associated error covariances for an /spl alpha/-/spl beta/-/spl Gamma/ filter with a piecewise constant jerk as a maneuver model. While the results given in that article are correct, the gains and error covariances can be found in a much simpler manner. The simplified expressions for the gains and the error covariances are given, along with the code for a simple program that computes the gains for a given tracking index.<>
