Abstract
The report presents the generalization of Luenberger's observer to discrete time-delayed deterministic and stochastic systems, when the detected signals may contain noise alone, and only the probability of occurrence of such cases is known to the estimator. The solution encompasses the special cases of Kalman's optimal filter, Nahi's filter, Tse and Athans and Leondes and Novak's reduced-order observers. The design of a reduced-order observer is illustrated using a radar-tracking problem.
