FIELD: radio engineering, communication.
SUBSTANCE: invention relates to radio engineering and can be used to determine radio characteristics of large-size antennae for spacecraft without direct measurement thereof. The method includes constructing a three-dimensional model of a reflector using a high-precision contactless laser scanner Leica Lazer Radar LR200, constructing three-dimensional amplitude and phase directional patterns of the irradiator based on the measured principal cross-sections of the amplitude and phase directional patterns, calculating energy characteristics of the large-size antennae using a developed program-algorithm system.
EFFECT: high reliability of measurements of radio characteristics of large-size antennae for spacecraft in conditions exposed to the Earth's gravity, enabling investigation of the relationship between required accuracy of the reflector profile and the operating frequency range without direct measurements in the far zone.
