Устройство относится к радиотехнике и может быть использовано для повышения помехозащищенности радиоэлектронных средств различного назначения и позволяет повысить помехозащищенность тропосферной линии связи, на которой автоматически выбирается рабочая частота за счет адаптации к организованной незамирающей помехе, несовпадающей с направлением прихода полезного сигнала. Адаптивная помехозащищенная линия связи включает: передающую и приемную сторону и канал обратной связи. На приемной стороне введены анализатор помеховой обстановки и решающее устройство. Повышение помехозащищенности адаптивной линии связи достигается за счет выбора на линии связи такой рабочей частоты, при которой с выхода антенн сигналы помехи имеют относительный сдвиг 180° и перевода тропосферной линии на эту частоту. После изменения местоположения источника помехи производится уточнение частоты и перестройка передающего и приемного устройств.The device relates to radio engineering and can be used to improve the noise immunity of radio electronic equipment for various purposes and improves the noise immunity of the tropospheric communication line, which automatically selects the operating frequency by adapting to organized non-transient interference that does not match the direction of arrival of the useful signal. The adaptive anti-interference link includes: the transmitting and receiving side and the feedback channel. At the receiving side, an interference analysis analyzer and a resolver are introduced. The increase in the noise immunity of the adaptive communication line is achieved by choosing the operating frequency on the communication line, at which from the antenna output the interference signals have a relative shift of 180 ° and transfer the tropospheric line to this frequency. After changing the location of the source of interference, the frequency is refined and the transmitter and receiver are rearranged.
