Abstract
1. Способ пассивной локации подвижного объекта, основанный на приеме сигналов, излучаемых объектом, оптимальной обработке принятых сигналов, отличающийся тем, что принимают излучаемые объектом сигналы радиолокационными станциями, разнесенными в пространстве, вычисляют взаимную корреляционную функцию принятых радиолокационными станциями сигналов, предварительно осуществив транспонирование частоты в тракте прохождения сигнала одной из радиолокационных станций, сигнал другой радиолокационной станции при вычислении взаимной корреляционной функции используют в качестве опорного, по превышению импульсного значения корреляционной функции сигналов над порогом судят о наличии объекта в обозреваемом пространстве.2. Способ по п. 1, отличающийся тем, что транспонирование частоты в тракте прохождения сигнала радиолокационной станции осуществляют путем мультипликативного преобразования частотного спектра сигнала.3. Способ по п. 1 или 2, отличающийся тем, что вычисление взаимной корреляционной функции сигналов, принятых радиолокационными станциями, разнесенными в пространстве, осуществляют многократно, варьируя значение коэффициента транспонирования частоты сигнала, после вычисления взаимной корреляционной функции сигналов, выбирают выходной сигнал с максимальным импульсным значением.1. The method of passive location of a moving object, based on the reception of signals emitted by the object, the optimal processing of received signals, characterized in that the signals emitted by the object are received by radar stations spaced in space, the mutual correlation function of the signals received by the radar stations is calculated, having previously transposed the frequency into the signal path of one of the radar stations, the signal of the other radar station when calculating the cross correlation The function is used as a reference function; judging by the excess of the pulse value of the correlation function of the signals above the threshold, one judges the presence of an object in the surveyed space. 2. The method according to claim 1, characterized in that the transposition of the frequency in the signal path of the radar station is carried out by multiplicatively converting the frequency spectrum of the signal. The method according to claim 1 or 2, characterized in that the calculation of the mutual correlation function of the signals received by the radar stations spaced in space is carried out repeatedly, varying the value of the transposition coefficient of the signal frequency, after calculating the mutual correlation function of the signals, select the output signal with the maximum pulse value .
