BUILT-IN SENSOR FOR INTERCEPTING RADIOELECTRIC COM/RAD EMISSIONS

The invention relates to a sensor (10) for analysing radar RAD emissions and communication COM emissions, comprising: a common receiving stage (100) for digitalising an incident signal; a common primary analysis processing stage (200) for pre-processing the digitalised signal in order to determine a plurality of primary characteristics of the incident signal; and a secondary analysis processing stage (300) comprising a chain (400) of processing procedures for the pretreated digitalised signal, dedicated to COM emissions, and a chain (500) of processing procedures for the pretreated digitalised signal, dedicated to RAD emissions, the primary analysis processing stage (200) comprising a discrimination module for applying the pre-processed digitalised signal at the start of the chain (400) dedicated to the COM emissions and/or at the start of the chain (500) dedicated to the RAD emissions, on the basis of the primary characteristics determined for the incident signal.
