SHORTWAVE RECEIVING MULTICHANNEL ANTENNA SYSTEM (RMAS) Russian patent published in 2011 - IPC H01Q21/00 

FIELD: radio engineering.

SUBSTANCE: device has N receiving multichannel analogue-digital channels (MADC), each having an antenna unit, a MADC analogue unit consisting of M high-frequency channels, outputs of which are connected to M inputs of a MADC digital unit, each of which has M digital channels, outputs of the digital channels of the MADC digital unit are connected to data inputs of a MADC multiplexer, the output/inpupt of which is the output/input of the MADC, N output/input signals of the MADC multiplexer of each of the MADC are transmitted through MADC partial communication lines which are the communication line of the RMAS local area network to N inputs/outputs of the multiplexer of the RMAS local area network, the input/output signal bus of which is connected to corresponding outputs/inputs of a signal processing unit, each of the M digital channels of the MADC digital unit has an analogue-to-digital converter (ADC), the input of which is the input of the digital channel, and the output is connected to the input of the digital converter from a set of digital channels of the MADC digital unit, respectively, also included is a reference signal unit, the outputs of which are connected to inputs of the multiplexer of the RMAS local area network and the signal processing unit, respectively, M output buses of the signal processing unit are data outputs of the RMAS, and the control signal input/output of the signal processing unit the control input/output of the RMAS as a whole.

EFFECT: high noise immunity of the system when exposed to powerful spontaneous noise, rapid change of the position of the formed beam patterns, low level of diffraction maxima of resultant beam patterns and high accuracy of forming beam patterns.
