Abstract

Использование: радиотехника, СВЧ широкополосные системы радиосв зи. Сущность изобретени : адаптивное устройство подавлени  помех содержит две антенны 1, 4, пол ризационный селектор 5, три разделительных фильтра 3, 7 и 8, регул торы комплексных коэффициентов передачи 9, N сумматоров 10, суммирующий фильтр .11, приемный блок 12, блок 13 разделени  сигналов и помех, два квадратичных детектора 14, 15 и формирователь комплексных весовых множителей. Целью изобретени   вл етс  увеличение количества одновременно подавл емых узкополосных помех с различной пол ризацией и увеличение отношени  мощности полезного сигнала к мощности помех.2 ил.Usage: radio engineering, microwave broadband radio communication systems. The inventive adaptive interference suppression device comprises two antennas 1, 4, a polarization selector 5, three isolation filters 3, 7 and 8, complex gain controllers 9, N adders 10, a summing filter .11, a receiving unit 12, a block 13 separation of signals and interference, two quadratic detectors 14, 15 and a shaper of complex weighting factors. The aim of the invention is to increase the number of simultaneously suppressed narrowband interference with different polarization and to increase the ratio of the useful signal power to the interference power.
