Principles of optimization of band elimination of passive interference in conditions of a priori parametric uncertainty of their spectral & correlation characteristics have been reviewed. A procedure is proposed for optimizing of systems for coherent signal processing based on a combination of a band elimination and a multichannel filter, such procedure in conditions of a priori uncertainty entails adaptive rearrangement of the weight coefficients of the filters and makes it possible to approach the maximum efficiency of the system. The analysis of the processing systems efficiency, which was performed on the basis of asymptotic properties of evaluations of the maximum likelihood, establishes the relationship between interference cancellation in the system and errors in adaptation to unknown correlation parameters of the interference. The relationships obtained as a result of the analysis make it possible to select the scope of the learning sample depending on the preset value of the adaptation loss, the spectral & correlation properties of the passive interference and the structure of the coherent signal processing system.
