MULTICHANNEL RADIO MONITORING DEVICE Russian patent published in 2014 - IPC H01Q21/00 G01S13/02 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to radio electronics. The multichannel radio monitoring device comprises an antenna array consisting of N antennae, outputs of which are connected in series to N analogue receiving units, N analogue-to-digital converters (ADC) and N DDC, as well as k controlled-delay data storage units. The present invention comprises the following steps: first, preliminary processing of a wideband signal through frequency decomposition thereof using full reconstruction analysis filter banks, reducing redundancy and storage during a required time for delayed access; second, picking up narrow-band signals by reading from the controlled-delay data storage units of the required frequency-time fragment of the wideband signal, decompression thereof in data decompression units; reconstructing, using synthesis filter banks, space-time processing in space-time signal processing units and transmitting signals to the user via interfaces with client signal processing means for end processing thereof.

EFFECT: providing access to narrow-band signals in delayed mode and increase in number of concurrently operating receiving channels.
