FIELD: antenna engineering.
SUBSTANCE: one of proposed design alternates is spatial phased antenna array made in the form of matrix that has driving mixer supplied with driving-frequency signals f and Δf, whose service-frequency output signals f1 = f + Δf and f2 = f - Δf are passed through respective phase shifters to matrix lines and columns, respectively; disposed at intersection points of matrix lines and columns are mixers; outputs of each of them are connected to respective circulator connected through respective receiving amplifier to first input of heterodyne mixer whose second input is fed with heterodyne frequency and output is connected to first input of receiving mixer; second input of the latter is connected to output of respective mixer; outputs of receiving mixers are connected to signal adding device.
EFFECT: minimized quantity of controlled phase shifters.
