Abstract

FIELD: radio engineering, radio dispatching points of monitoring to analyze signal situation within region, automatic search and detection of radio stations regularly changing their working frequencies. SUBSTANCE: for increase of probability of detection of communication channels with frequent change of working frequencies by observed radio stations device for automatic search has reference frequencies unit 1, receiver 2, detector 3, synthesizer 4 of frequencies, N band-pass filters 5, N threshold units 6, first register 7, second register 8, comparator 9, programmable permanent storage 10, inverter 11, generator 12 of clock frequency, wide-band antenna amplifier 13. This circuit makes it possible to identify observed radio station during its scanning over several fixed frequencies by storage of conditions of signal situation in entire range of frequencies used by radio station up to moment of change of working frequency by transmitter and its comparison with condition of range after change of frequency. Receiver is tuned only to that frequency on which signal appears at given time moment. EFFECT: increased probability of detection of communication channels with frequency change of working frequencies by observed radio stations. 1 cl, 5 dwg

Изобретение относится к области радиотехники и может быть использовано в радиодиспетчерских пунктах мониторинга для анализа сигнальной обстановки в регионе, для автоматического поиска и обнаружения радиостанций, постоянно сменяющих рабочие частоты. Решаемая изобретением задача - повышение вероятности обнаружения каналов связи при частых сменах рабочих частот наблюдаемыми радиостанциями. Для достижения указанной задачи устройство автоматического поиска радиостанций включает блок опорных частот 1, приемник 2, регистратор 3, синтезатор частот 4, N полосовых фильтров 5, N пороговых устройств 6, первый регистр 7, второй регистр 8, блок сравнения 9, перепрограммируемое постоянное запоминающее устройство 10, инвертор 11, генератор тактовой частоты 12, широкополосный антенный усилитель 13. При такой схеме оказывается возможным идентифицировать наблюдаемою радиостанцию при ее сканировании по нескольким применяемым фиксированным частотам путем запоминания состояний сигнальной обстановки всего диапазона используемых радиостанцией частот до момента смены передатчиком рабочей частоты и сравнения с состоянием диапазона после ее смены. Настройка приемника производится только на ту частоту, на которой появился сигнал в данный момент времени.The invention relates to the field of radio engineering and can be used in radio dispatch monitoring points for the analysis of the signal situation in the region, for the automatic search and detection of radio stations that constantly change operating frequencies. The problem solved by the invention is to increase the likelihood of detecting communication channels with frequent changes in operating frequencies by the observed radio stations. To achieve this task, the device for automatic search for radio stations includes a reference frequency unit 1, receiver 2, recorder 3, frequency synthesizer 4, N bandpass filters 5, N threshold devices 6, first register 7, second register 8, comparison unit 9, reprogrammable read-only memory 10, inverter 11, clock generator 12, broadband antenna amplifier 13. With this scheme, it is possible to identify the observed radio station when it is scanned for several fixed frequencies used m by storing the signal states of the entire range of conditions used by the radio frequency transmitter until the change of the operating frequency band and comparing with the state after the shift. The receiver is tuned only to the frequency at which the signal appeared at a given time.
