Abstract
Фазовый способ пеленгации, основанный на приеме сигналов на две антенны, удаленные друг от друга на расстояние d, усилении и ограничении, отличающийся тем, что вводят третью приемную антенну на произвольном расстоянии от первой и второй антенн, усиливают и ограничивают входную смесь сигналов, принятых третьей антенной, перемножают смесь сигналов с третьей антенны с сигналом синтезатора частот, выделяют смесь сигналов на промежуточной частоте, снова перемножают выделенную смесь сигналов с входной смесью сигналов с первой антенны, выделяют взаимную комбинационную составляющую на комбинационной частоте, возникающую при взаимодействии на нелинейном элементе сигнала из смеси сигналов с первой антенны и помехи из смеси сигналов с третьей антенны, аналогичное преобразование смеси сигналов и выделение взаимной комбинационной составляющей на той же комбинационной частоте производят для второй антенны, затем для выделенной пары комбинационных составляющих на одной и той же частоте осуществляют измерение разности фаз, соответствующей времени запаздывания сигнала при приеме на первую и вторую антенны, затем вычисляют пеленгационный угол источника излучения, при этом решение о наличии комбинационной составляющей на выходе фазового канала принимают при превышении уровнем сигнала заранее установленного порога, для выделения определенной комбинационной составляющей в каждом из фазовых каналов используются неперестраиваемые полосовые фильтры, при этом сканирование по диапазону осуществляется программируемым синтезатором частоты.Phase direction finding method, based on the reception of signals at two antennas remote from each other by a distance d, amplification and limitation, characterized in that the third receiving antenna is introduced at an arbitrary distance from the first and second antennas, amplify and limit the input mixture of signals received by the third antenna, multiply the mixture of signals from the third antenna with the signal of the frequency synthesizer, extract the mixture of signals at the intermediate frequency, again multiply the selected mixture of signals with the input mixture of signals from the first antenna, select m is the reciprocal Raman component at the Raman frequency that occurs when a signal interacts on a non-linear element from a signal mixture from the first antenna and interference from a signal mixture from the third antenna, a similar conversion of the signal mixture and separation of the reciprocal Raman component at the same Raman frequency is performed for the second antenna, then for a selected pair of combinational components at the same frequency, the phase difference is measured corresponding to the signal delay time at reception on the first and second antennas, then the direction finding angle of the radiation source is calculated, and the decision on the presence of the combinational component at the output of the phase channel is made when the signal level exceeds a predetermined threshold, to select a specific combinational component in each phase channel, non-tunable bandpass filters are used, while range scanning is carried out by a programmable frequency synthesizer.
