FIELD: antenna.
SUBSTANCE: invention relates to antenna engineering, primarily, in microwave range. For this purpose, method of determining parameters of antenna multichannel radar signals arriving on each of channels, digitized and parameter of antenna is found, defined as sum of actual (imaginary) part of ratio of two beam patterns, obtained from different sections of antenna, and absolute value of this part is called trans-function and with help of trans-function by multiplication is limited to required value of investigated area. Using trans-function can be, in particular, to produce from antennae with opening data equivalent of beam pattern width in 4 times more narrow than width of classic angular pattern on half value of power with uniform phase distribution of field in aperture.
EFFECT: technical result is high resolution of antenna and high accuracy of direction-finding of targets.
