Abstract
Фазовый способ формирования провалов в диаграмме направленности плоской фазированной антенной решетки (ФАР), основанный на оценке уровня исходной диаграммы направленности N-элементной ФАР, выделении в раскрыве двух M-элементных подрешеток и введении фазовых поправок, со знаком минус для элементов одной подрешетки и со знаком плюс для элементов другой подрешетки, отличающийся тем, что оценку уровня исходной диаграммы направленности N-элементной ФАР осуществляют в К заданных направлениях, которые задают двумя угловыми координатами θнапр i и φнапр i, выбирают К эквивалентных линейных раскрывов, углы которых равны значениям координат К направлений φнапр i, вычисляют возбуждение этих раскрывов, после выделения в каждом эквивалентном линейном раскрыве двух M-элементных подрешеток, расположенных на его краях, величины их фазовых поправок выбирают равными по абсолютному значению из условия заданных глубины, ширины и координаты θнапр i провала, фазы элементов ФАР, образующих M-элементные подрешетки К эквивалентных линейных раскрывов, изменяют на величину фазовых поправок этих подрешеток, при условии что M-элементные подрешетки К эквивалентных линейных раскрывов формируются несовпадающими элементами ФАР, где ! θнапр i и φнапр i - заданные направления в сферической системе координат, а θнапр i отсчитывается от нормали к плоскости раскрыва ФАР; ! i - порядковый номер заданного направления, i=1…К; ! К - количество заданных направлений. The phase method of forming dips in the directivity pattern of a flat phased antenna array (PAR), based on the assessment of the level of the initial radiation pattern of the N-element PAR, highlighting two M-element sublattices in the aperture and introducing phase corrections, with a minus sign for elements of one sublattice and with a sign plus for elements of another sublattice, characterized in that the level of the initial radiation pattern of the N-element headlamp is estimated in K specified directions, which are defined by two angular coordinates θ i and φdirection i, choose K equivalent linear openings whose angles are equal to the coordinates of the K directions of directions φnapi i, calculate the excitation of these openings, after selecting in each equivalent linear aperture two M-element sublattices located at its edges, the values of their phase corrections are chosen equal according to the absolute value from the condition of the given depth, width and coordinate θ for i failure, the phases of the PAR elements forming M-element sublattices of K linear linear openings are changed by the magnitude of the phase corrections of these n of the lattices, provided that the M-element sublattices of the equivalent linear openings are formed by mismatched PAR elements, where! θdirection i and φdirection i are given directions in the spherical coordinate system, and θdirection i is measured from the normal to the aperture plane of the PAR; ! i - serial number of a given direction, i = 1 ... K; ! To - the number of specified directions.
