In article formulas for estimation extremely achievable easing interfering a signal, subject to casual influence of the environment of distribution are received. The received parities allow to estimate limiting indemnification possibilities interfering fluctuations as consideration is spent with reference to a case of their passage through processing devices in which the signal/hindrance is optimum by criterion of a maximum of the relation. With reference to a case of influence of one hindrance, in conditions when radius of correlation of phase fluctuations much more the sizes of an estimation, expression for complex amplitude of spatial weight function is received. Using this expression, the function chart of channels of spatial processing is developed and easing of capacity of a hindrance by the offered device is estimated.
