DEVICE FOR PICKING UP TELEGRAPH SERVICE RADIO SIGNALS Russian patent published in 1994 - IPC

Abstract RU 2009615 C1

FIELD: radio communication. SUBSTANCE: device has several distant picking-up channels. Each channel has spatial-polarization filter. Picking-up channels are integrated into a device by means of coherent weight addition system. The channels are separated in such a manner that fadings of amplitude of received field are not correlated. Device provides noise immunity of reception in ionospheric and tropospheric communication channels if multipath interference is available in the channels which differs from useful signal by azimuthal falling angle being unknown apriori. EFFECT: improved noise immunity. 4 dwg
