Description: In the conditions of influence of hindrances in the radio-location stations with phased antenna arrays it is assumed to carry out defence by a calculation peak-phase distributing, which allows to form the diagram of orientation with failures in the set directions. The algorithm of rapid calculation is offered peak-phase distributing. An algorithm does not contain procedure of appeal of matrices of wave fronts, that abbreviates time of calculations considerably. The change of the directed properties of aerial is analysed. It is assumed to apply a method in the radio engineerings systems with phased antenna arrays, where it is necessary to repress active and passive hindrances, accepted from unknown directions in area of sidelobes of diagram of orientation of phased antenna arrays.
