METHOD OF FORMING COMPENSATION BEAM PATTERN IN FLAT ELECTRONICALLY CONTROLLED-BEAM ANTENNA ARRAY

摘要

FIELD: radio engineering, communication.;SUBSTANCE: method includes receiving signals with antenna elements of a flat antenna array with electronic beam scanning and summation of said signals to form a highly directional scanning beam pattern of the flat antenna array using selected complex amplitudes of the antenna element, taking into account the required overshooting of the level of the compensation beam pattern of the level of sidelobes of the highly directional scanning beam pattern. A weakly directional beam pattern is formed by summing the signals of the antenna elements situated in central orthogonal lines of the flat antenna array with complex amplitudes corresponding to the complex amplitudes of the antenna elements of the flat antenna array in the direction of the source of the useful signal. The compensation beam pattern is formed by subtracting the signal corresponding to the highly directional scanning beam pattern from the signal corresponding to the weakly directional beam pattern, multiplied by a weighting coefficient which is equal to the ratio of the standard highly directional scanning and weakly directional beam patterns with beam orientation of the flat antenna array in the direction of the normal to the aperture plane.;EFFECT: providing the required overshooting of the level of the compensation beam pattern of the level of sidelobes of the highly directional scanning beam pattern of the flat antenna array in a wide sector of angles while maintaining sensitivity of the receiving system.;12 dwg
