Abstract

The relationships for optimizing a selective estimate of the correlation matrix of classical (initial and modified) and fast projection algorithms in a complex noise situation were determined. Model investigations on the comparison of the resolution of classical optimized algorithms with the characteristics of two variants of fast projection algorithms were performed. The algorithms were compared using the criterion of a decrease in the time and reduction of the angular zone of the loss of a contact with a weak target when it intersects the path of an intense interfering signal. The relationships that correspond to the most economical realization of the fast algorithm were determined.
