Abstract
1. Способ обнаружения и пеленгации источников радиоизлучения на одной частоте, с априорно неизвестной формой сигнала, включающий в себя прием сигналов посредством многоэлементной антенной решетки, синхронное преобразование принятых сигналов в комплексные цифровые сигналы, преобразование цифровых сигналов в сигнал амплитудно-фазового распределения, описывающий распределение амплитуд и фаз на элементах многоэлементной антенной решетки, генерацию двумерного детерминированного вектора волнового фронта q комплексной фазирующей функции Q размером N×L, зависящего от заданной частоты приема и определяющего значения комплексных амплитуд для гармонического источника радиоизлучения приходящего с каждого направления сканирования, где N - число антенных элементов, L - число направлений сканирования, соответствующих заданным потенциально возможным направлениям прихода сигнала, с угловыми координатами γ…γ, отличающийся тем, что получение многосигнального углового спектра мощности Р, представляющего собой распределение квадратов амплитуд по пеленгам α и β, обеспечиваем минимизацией функции максимальною правдоподобия, путем обеспечения сходимости по времени накопления цифровых отсчетов, с учетом использования рекурсивного представления для оценки сигнальной и корреляционной матриц сигналов и по полученному многосигнальному угловому спектру мощности строим пеленгационную панораму, по которой определяем количество, интенсивности, и пеленги источников радиоизлучения.2. Способ обнаружения и пеленгации источников радиоизлучения на одной частоте по п.1, отличающийся тем, что дополнительно определяют крите�1. The method of detection and direction finding of radio sources at the same frequency, with an a priori unknown waveform, which includes receiving signals through a multi-element antenna array, synchronously converting the received signals into complex digital signals, converting digital signals into an amplitude-phase distribution signal describing the distribution of amplitudes and phases on the elements of a multi-element antenna array, generating a two-dimensional determinate wavefront vector q of a complex phasing function and Q of size N × L, depending on the given reception frequency and determining the complex amplitudes for the harmonic source of radio emission coming from each scanning direction, where N is the number of antenna elements, L is the number of scanning directions corresponding to the given potential signal arrival directions, with angular coordinates γ ... γ, characterized in that obtaining a multi-signal angular power spectrum P, which is the distribution of the squared amplitudes along bearings α and β, provides a mini by minimizing the maximum likelihood function, by ensuring convergence in the time of accumulation of digital samples, taking into account the use of the recursive representation for evaluating the signal and correlation matrix of signals and using the obtained multi-signal angular power spectrum, we construct a direction-finding panorama from which we determine the amount, intensities, and bearings of radio emission sources. 2 . The method for the detection and direction finding of radio sources at a single frequency according to claim 1, characterized in that they further define the criterion
