Abstract

Для патентования представляется блок-схема полуактивной радиолокационной станции (РЛС) с использованием подсвета зоны радиолокационного наблюдения излучением базовых станций сотовой связи (БССС), которая содержит 3 приемных канала: основной, подключенный к направленной антенне РЛС; два опорных, подключенных к направленным на БССС антеннам. Выходы приемных каналов подключены к соответствующим входам пространственного автокомпенсатора, после чего для спектральной режекции проникающего по боковым лепесткам диаграммы направленности антенны РЛС прямого сигнала от БССС осуществляется его сжатие по спектру за счет перемножения с сигналом опорного канала и подавление режекторным фильтром. Для выделения отраженного радиолокационного сигнала на фоне шумов приемников и остатков проникающего сигнала осуществляется обработка в объединенных по входу М дальностных каналах, каждый из которых содержит перемножитель и N объединенных по входу доплеровских узкополосных фильтров. При этом для демодуляции радиолокационных сигналов с учетом их перемодуляции в первом перемножителе, второй вход перемножителя каждого дальностного канала соединен с соответствующим выходом специального формирователя опорных сигналов, входом подключенного к одному из опорных приемных каналов. За счет дополнительной спектральной режекции повышается эффективность подавления проникающего сигнала - основного помехового сигнала РЛС и достигается увеличение дальности ее действия.For patenting, a block diagram of a semi-active radar station (RLS) is presented using the radar observation zone illumination by base station cellular communication (BSSS) radiation, which contains 3 receiving channels: the main one connected to a directional radar antenna; two support, connected to the antennas directed to the BSSS. The outputs of the receiving channels are connected to the corresponding inputs of the spatial autocompensator, after which, for spectral rejection of the direct signal from the BSSS penetrating the side lobes of the radar antenna of the radar, it is compressed by spectrum due to the multiplication with the reference channel signal and suppressed by the notch filter. To highlight the reflected radar signal from the background noise of the receivers and the remnant of the penetrating signal, the processing is carried out in the combined M channels, each of which contains a multiplier and N combined Doppler narrowband filters at the input. Moreover, for demodulation of radar signals, taking into account their overmodulation in the first multiplier, the second input of the multiplier for each distance channel is connected to the corresponding output of a special driver of the reference signals, the input connected to one of the reference receiving channels. Due to the additional spectral rejection increases the effectiveness of the suppression of the penetrating signal - the main interfering signal of the radar and is achieved by increasing its range.
