FIELD: radio equipment.
SUBSTANCE: invention relates to microwave equipment, particularly to phased antenna arrays (PAA), and can be used in radar systems with electric beam scanning. Technical effect is achieved due to the fact that the beam control system (BCS) consists of several structural units, made in the form of printed-circuit boards installed in the housings, each of which serves as a power module or control module, arranged inside the housing PAA between the linear modules and the rear wall of the housing PAA around the monopulse feed (MPF) outside the radiation area PAA, wherein structural replaceable units are rigidly fixed by ends on rear wall of housing PAA, wherein each element PAA by one output is connected to one conductor of multi-conductor printed circuit board, and the other to ground bus installed on base of linear module.
EFFECT: simplified design, reduced labor intensity, PAA repairability, as well as reduced cross dimensions of PAA.
