The technical results contained in this report include Formulas for optimum processing of complex samples when the sign als has known and unknown phase structure Formulas for optimum processing of complex sample amplitude, phases, and symmetric phase-differences when the signal has known and unknown phase structure Formulas for the optimum processing of the frequency domain representation of the signal samples when the signal is narrowband explicit formulas for processing samples when the statics are modeled by either non- central or central mixture models for which the parameters are estimated or implicit Processing gain over traditional processing bounds and estimates in terms of model parameters for the above algorithms when the statics are modeled by either non-central or central mixture models Comparison of processing gain bounds and estimates with performance estimates obtained through simulations for two- and three-state mixture models Simulation results for averages of the transformed samples and results for the loss of performance due to target motion for processing at the output of a beamformer.
