Abstract
1. Способ поляризационно-независимого обнаружения и локализации широкополосных радиосигналов, заключающийся в том, что принимают радиосигналы N вертикально поляризованными антеннами в заданной полосе частот, синхронно преобразуют ансамбль принятых сигналов в цифровые сигналы, из цифровых сигналов на каждой l-й частоте полосы приема формируют сигнал вертикально поляризованной компоненты комплексного амплитудно-фазового распределения (АФР), отличающийся тем, что дополнительно принимают радиосигналы N горизонтально поляризованными антеннами, синхронно преобразуют ансамбль принятых сигналов в цифровые сигналы, из которых на каждой l-й частоте полосы приема формируют сигнал горизонтально поляризованной компоненты комплексного АФР, объединяют сигналы вертикально поляризованной и горизонтально поляризованной компонент в сигнал двухкомпонентного комплексного АФР , по сигналам двухкомпонентного комплексного АФР выполняют обнаружение и частотно-пространственную локализацию радиосигналов. ! 2. Способ по п.1, отличающийся тем, что обнаружение и частотную локализацию радиосигналов осуществляют путем формирования квадратов модулей комплексных коэффициентов взаимной корреляции сигнала двухкомпонентного комплексного АФР на частоте l с сигналом двухкомпонентного АФР на всех остальных частотах l' полосы приема, сравнивают квадраты модулей коэффициентов взаимной корреляции K(l,l') с порогом, радиосигналы с частотами, на которых превышен порог, объединяют в сигнал, который идентифицируют как i-й обнаруженный радиосигнал, принадлежащий одному передатчику, и фиксируют полосу частот его локализации. ! 3. Спос 1. The method of polarization-independent detection and localization of broadband radio signals, which consists in receiving radio signals N by vertically polarized antennas in a given frequency band, synchronously converting the ensemble of received signals into digital signals, generating a signal from digital signals on each l-th frequency of the reception band vertically polarized components of the complex amplitude-phase distribution (AFR), characterized in that they additionally receive radio signals N horizontally polarized tones, synchronously transform the ensemble of received signals into digital signals, from which the signals of the horizontally polarized components of the complex AFR are formed on each l-th frequency of the reception band, the signals of the vertically polarized and horizontally polarized components are combined into the signal of a two-component complex AFR, and the signals are detected by a two-component complex AFR and frequency-spatial localization of radio signals. ! 2. The method according to claim 1, characterized in that the detection and frequency localization of the radio signals is carried out by forming the squares of the modules of the complex coefficients of cross-correlation of the signal of two-component complex AFR at a frequency l with the signal of two-component AFR at all other frequencies l 'of the reception band, comparing the squares of the coefficient modules correlation of K (l, l ') with the threshold, radio signals with frequencies at which the threshold is exceeded are combined into a signal that is identified as the ith detected radio signal belonging to one transmitter, and fix the frequency band of its localization. ! 3.
