FIELD: radio engineering.
SUBSTANCE: invention relates to radio engineering and can be used in radar systems with a phased antenna array (PAA) with spatial excitation for direction finding of radiation sources with increased resolution. To do this, a phase distribution is introduced on the elements of the feed system, which compensates for the distortion of the phase front of the electromagnetic wave of the radiation source, which occurs due to the difference in the path of the waves from each element of the array to each feed and the presence of a phase distribution on the elements of the phased array.
EFFECT: increase in the accuracy of determining the bearing of radiation sources.
