FIELD: the invention refers to antenna technique.
SUBSTANCE: mode of separate forming of nulls in summary and difference diagrams of the direction of a mono impulse phase array antenna is in singling out of the initial array antenna of an adaptive sub array having adaptive oscillators, in division of signals received by each oscillator into two channels, in weighing of signals with the help of complex weighing devices, in summing up of the signals from the outputs with the phases of the same names providing formation of two beams of the mono impulse group deflected from the equisignal direction along the generalized coordinate and in a following formation of a summary and a difference patterns of direction. At that the adaptive sub array is singled out on one of the edges of the initial phase array antenna and the sub array consists of adaptive 2R oscillators.
EFFECT: increases accuracy of definition of angular coordinates of objects.
