Способ энергетической оптимизации моноимпульсных антенных решеток с совместным формированием лучей, основанный на взвешивании сигналов, принятых каждым излучателем, с помощью комплексных весовых коэффициентов, разделении этих сигналов на два канала, суммировании сигналов с одноименных выходов делителей с соответствующим прогрессивно нарастающим и убывающим фазовым сдвигом, обеспечивающим отклонение каждого луча на угол ±ΔΘ, и последующем образовании суммарной и разностной диаграмм направленности, в соответствии с которым комплексные весовые коэффициенты находят как главный вектор пучка эрмитовых форм, соответствующий наибольшему характеристическому числу пучка, при определении которого используют информацию о направлении на источник сигнала и о распределении источников помех, а в качестве первой и второй эрмитовых форм пучка выбирают соответственно мощность сигнала в суммарном канале и сумму мощностей шумов и помех в лучах моноимпульсной группы, отличающийся тем, что комплексные весовые коэффициенты части N-2M элементов моноимпульсной антенной решетки, где N - общее число элементов моноимпульсной антенной решетки, а 2М - число элементов с независимыми комплексными весовыми коэффициентами, принимают равными произведению исходных весовых коэффициентов, обеспечивающих ориентацию равносигнального направления на источник сигнала, на общий для этих элементов комплексный весовой коэффициент Ip, определяемый из решения задачи оптимизации, после чего комплексные весовые коэффициенты всех элементов нормируют к значению Iр, в связи с чем весовые коэффициенты неадаптируемых N-2M элементов не изменяют, а ранг эрмитовых форм понижают до порядка 2М+1.A method of energy optimization of monopulse antenna arrays with joint beamforming, based on weighting the signals received by each emitter using complex weighting factors, dividing these signals into two channels, summing the signals from the outputs of the same divider with the corresponding progressively increasing and decreasing phase shift, which provides a deviation each beam at an angle of ± ΔΘ, and the subsequent formation of the total and difference radiation patterns, in accordance with which the complex Weighing coefficients are found as the main vector of the beam of Hermitian shapes, corresponding to the largest characteristic number of the beam, which is determined by using information about the direction to the signal source and the distribution of interference sources, and the signal power in the total channel is selected as the first and second Hermitian beam shapes, respectively, and the sum of the noise and interference powers in the rays of the monopulse group, characterized in that the complex weight coefficients of the N-2M part of the elements of the monopulse antenna array, where N is the total number of elements of a monopulse antenna array, and 2M is the number of elements with independent complex weighting coefficients, taken equal to the product of the initial weighting coefficients, providing orientation of the equal-signal direction to the signal source, and the complex weighting coefficient I p common for these elements, determined from the solution of the optimization problem , after which the complex weights of all elements are normalized to the value of I p , and therefore the weights of non-adaptable N-2M elements do not change t, and the rank of Hermitian forms is reduced to about 2M + 1.
