FIELD: antenna equipment.
SUBSTANCE: invention relates to antenna engineering. Method comprises receiving signals carried by an electromagnetic field, changing phase shifts of signals passing through one or more elements of the phased antenna array, measuring amplitude of the signal generated by the auxiliary antenna, in which the phased antenna array is located in an area where the electromagnetic field it receives is a flat electromagnetic wave, wherein setting a set of beam directions covering the phased antenna array visibility, and the opening plane, electric lengths from elements of which to the input of the measuring equipment are arbitrary, are placed at an angle relative to the front of the flat electromagnetic wave, changing by phase shifters phase shifts of signals passing through the phased antenna array elements, setting the phased antenna array beam into one of the set directions, measuring the signal amplitude, then repeating the operations, each time setting the phased antenna array beam successively to the other directions, signal amplitudes measured at each beam direction are multiplied by signal amplitudes predetermined for said directions from one element in the phased antenna array. To enable determination of the phased antenna array directional pattern with stationary installation of the tested phased antenna array in horizontal or inclined planes formation of a flat electromagnetic wave is carried out by an auxiliary antenna located on board a remotely piloted aircraft of quadcopter type, which in a hang-up mode together with an auxiliary antenna and a low-power transmitter on board is set to distance R≥2D2/λ, where: R – removal of auxiliary antenna array onboard from phased antenna array opening plane; D is the largest size of the phased antenna array opening; λ is operating wavelength; wherein the phased antenna array is located at an arbitrary angle relative to the horizon.
EFFECT: invention can be used to determine characteristics of phased antenna arrays.
