Abstract: Embodiments of the invention relate to a system for extracting and analyzing radioelectric signals of interest. It includes an integer number N of channels. Each channel Vi includes a receiver linked to an analog signals digital acquisition device delivering a digital signal SNi. Each channel Vi includes a bank of polyphase filters, extracting digital signals SEi from the digital signal SNi. The digital signals SEi each have a smaller frequency bandwidth than that of the digital signal SNi. The system includes at least one extracted digital signals distribution device suitable for receiving the digital signals SEi and distributing SEi to one or more processing and storage units. The processing and storage units are suitable for the analysis, characterization and storage of the digital signals received. Embodiments of the invention apply to the system for the radio-monitoring of radioelectric emissions in real time or in deferred time.
