Recently, new approaches for location of a target in nonoverlapping noise,
which are optimal in the maximum-likelihood sense, have been proposed. In
particular, different methods for deterministic or fluctuating targets have
been developed. We propose a unified and optimal processor for a target with
either known or unknown gray levels. We demonstrate the efficiency and robustness
of this method in comparison with previously developed processors.
