Book excerpt: This study presents the results of an investigation of the optimum signal processor for passive time delay estimation in a multisensor, multitarget environment. The target-sensor geometry is assumed stationary over the observation time interval. The performance of the optimum processor in terms of Cramer-Rao Lower Bound is presented. The relation between time delay estimation and localization parameter estimation is explored. The derivation of the optimum processor for joint time delay and power spectral estimation is also presented. Methods for improved time delay estimation in the presence of interference are investigated. Finally, a simple analytical expression for the Cramer-Rao Lower Bound for the joint cross-sensor time delay estimate from M sensor arrays is derived. (Author).
