Abstract

Methods of signals' wavelet denoising on the antenna array transducers' output are given. The comparative analysis of the algorithms efficiency based on the example of the algorithm for uncorrelated signals discrimination with the methods adaptation with formation of "zeros" of the radiation pattern in the directions of signals' sources outside the main maximum.
