Increasing the efficiency of communication with mobile and high-mobile objects in the conditions of a permanently getting more complicated signal-to-noise situation is connected to a complex modernization of all the elements of the system of communications. Particular attention here is paid to modernization of receiving antennas. Conventional antennas are now very often replaced by so-called adaptive antennas, capable of adapting themselves automatically to unknown signal-to-noise situation.

An algorithm for creating adaptive antennas functioning without a use of complete a priori information on useful signals is presented.
