Abstract : Time delay estimation forms the base from which passive localization and tracking may function accurately. This report considers both the practical and theoretical aspects of time delay estimation when classical optimal estimation techniques break down. Of special concern are two adverse situations: the underlying statistics of the observations are incompletely specified; and the observations contain a narrowband component. Additional keywords: minimax technique; robust Wiener filter; center of symmetry estimator; level-crossing; inhomogeneous Poisson.
