Abstract
1. Способ пеленгации источников радиоизлучения на одной частоте, включающий в себя прием многолучевого сигнала посредством многоэлементной антенной системы, синхронное преобразование ансамбля принятых сигналов, зависящих от времени и номера элемента антенной системы, цифровые сигналы, преобразование цифровых сигналов в сигнал амплитудно-фазового распределения, описывающий распределение амплитуд и фаз на элементах антенной системы, отличающийся тем, что получение пеленгов осуществляют посредством определения параметров экспоненциальных функций, содержащих функции пеленгов. ! 2. Способ по п.1, отличающийся тем, что определяют интервальные оценки амплитуд и пеленгов на основе дисперсий, полученных как дисперсии значений скалярных функций случайных аргументов для пеленгов и как дисперсии элементов вектора решения системы линейных алгебраических уравнений, полученного методом наименьших квадратов для амплитуд или мощностей.1. A method of direction finding radio-frequency sources at a single frequency, including receiving a multipath signal through a multi-element antenna system, synchronously converting an ensemble of received signals depending on the time and element number of the antenna system, digital signals, converting digital signals into an amplitude-phase distribution signal, describing distribution of amplitudes and phases on the elements of the antenna system, characterized in that the bearings are obtained by determining the parameters of the exposition ial functions containing bearings function. ! 2. The method according to claim 1, characterized in that the interval estimates of the amplitudes and bearings are determined based on variances obtained as variances of the values of scalar functions of random arguments for bearings and as variances of elements of a solution vector system of linear algebraic equations obtained by the least squares method for amplitudes or capacities.
