Abstract
Устройство радиотехнического контроля источников радиоизлучений, содержащее последовательно включенные первую приемную антенну, усилитель высокой частоты, делитель мощности, измеритель частоты и блок обработки результатов измерений и расчета пеленга, последовательно включенные вторую приемную антенну и второй усилитель высокой частоты, последовательно включенные третью приемную антенну, третий усилитель высокой частоты и первый измеритель разности фаз, второй вход которого соединен со вторым выходом делителя мощности, а выход - со вторым входом блока обработки результатов измерений и расчета пеленга, при этом фокальные оси приемных антенн параллельны и совпадают по направлению с направлением на центр сектора пеленгования, отличающееся тем, что в него введен второй измеритель разности фаз, первый вход которого соединен с выходом второго усилителя высокой частоты, второй - с третьим выходом делителя мощности, а выход - с третьим входом блока обработки результатов измерений и расчета пеленга, при этом блок обработки результатов измерений и расчета пеленга выполнен трехвходовым, а грубое значение Θг пеленга рассчитывается по формуле: ! ! где λ - длина волны контролируемого сигнала; ! а - расстояние между фокальными центрами первой и второй приемных антенн; ! Δφ - разность фаз контролируемого сигнала на выходах этих антенн.A device for radio-technical control of sources of radio emission, comprising a first receiving antenna, a high-frequency amplifier, a power divider, a frequency meter and a unit for processing results of measurements and bearing calculation, a second receiving antenna and a second high-frequency amplifier connected to a third receiving antenna, a third amplifier high frequency and the first phase difference meter, the second input of which is connected to the second output of the power divider, and the output is with the second input of the unit for processing the results of measurements and calculation of the bearing, while the focal axes of the receiving antennas are parallel and coincide in the direction to the center of the direction-finding sector, characterized in that a second phase difference meter is introduced into it, the first input of which is connected to the output of the second high-frequency amplifier , the second - with the third output of the power divider, and the output - with the third input of the processing unit of the measurement results and bearing calculation, while the processing unit of the measurement results and bearing calculation is performed t re-input, and the coarse value Θg of the bearing is calculated by the formula:! ! where λ is the wavelength of the controlled signal; ! a is the distance between the focal centers of the first and second receiving antennas; ! Δφ is the phase difference of the controlled signal at the outputs of these antennas.
