Abstract
Фазовый способ формирования провала в диаграмме направленности плоской фазированной антенной решетки (ФАР), основанный на оценке уровня исходной диаграммы направленности N-элементной ФАР в направлении помехи, выделении в раскрыве двух M-элементных подрешеток, расположенных на краях исходной, и введении фазовых поправок, со знаком минус для элементов одной подрешетки и со знаком плюс для элементов другой подрешетки, отличающийся тем, что для определения направления помехи задаются две угловые координаты θn, и φn, после оценки уровня исходной диаграммы направленности N-элементной ФАР вычисляют возбуждение ее эквивалентного линейного раскрыва в сечении, угол наклона которого равен значению координаты помехи φn, после выделения в эквивалентном линейном раскрыве двух M-элементных подрешеток, расположенных на его краях, величины фазовых поправок этих подрешеток выбирают равными по абсолютному значению из условия заданной глубины провала и координаты помехи θn, фазы излучателей плоской ФАР, образующих M-элементные подрешетки эквивалентного линейного раскрыва, изменяют на величину фазовых поправок, где θn, φn - координаты направления помехи в сферической системе координат. The phase method of forming a dip in the directivity pattern of a flat phased antenna array (PAR), based on assessing the level of the initial radiation pattern of the N-element PAR in the direction of interference, highlighting two M-element sublattices located at the edges of the source, and introducing phase corrections, with minus sign for elements of one sublattice and plus sign for elements of another sublattice, characterized in that for determining the direction of interference two angular coordinates θn, and φn are set, after evaluating the level, the outcome of the radiation pattern of the N-element phased array, the excitation of its equivalent linear aperture in the cross section is calculated, the tilt angle of which is equal to the value of the interference coordinate φn, after two M-element sublattices located at its edges are selected in the equivalent linear aperture, the phase corrections of these sublattices are chosen equal to the absolute value from the condition of the given depth of failure and the coordinate of the interference θn, the phases of the flat-headlamp emitters forming the M-element sublattices of the equivalent linear aperture, are changed by Ichin phase corrections where θn, φn - the coordinates of the direction of interference in a spherical coordinate system.
