PANORAMIC BROAD-BAND RADIO RECEIVING DEVICE Russian patent published in 2010 - IPC H03J7/32 

FIELD: radio engineering.

SUBSTANCE: in panoramic broad-band radio receiving device containing in-series connected high-frequency receiving path, analogue-to-digital converter, digital filter of the main selection and digital demodulator, according to invention the digital filter of the main selection and digital demodulator are included in digital processing unit of signals, which in addition is equipped with digital signal accumulator, to panoramic broad-band radio receiving device there additionally introduced is electrically switched attenuator and shaper of control action; at that, inlet of electrically reconfigurable attenuator is the inlet of panoramic broad-band radio receiving device, and its outlet is connected to the inlet of high-frequency receiving path, control input of electrically controlled attenuator is connected to the output of shaper of control action, the input of which is connected to output of synchronisation signals of digital processing unit of signals, input of digital signal accumulator is connected to output of digital demodulator, and its output is the output of panoramic broad-band radio receiving device.

EFFECT: avoiding false targets in panoramic broad-band radio receiving device due to intermodulation constituent parts appearing at action of interference of high level.
