Abstract: This sensor (10), capable of analyzing radar emissions RAD and communication emissions COM, includes: a reception stage (100), shared and capable of digitizing an incident signal; a primary analysis processing stage (200), shared and capable of preprocessing the digitized signal to determine a plurality of primary characteristics of the incident signal; and a secondary analysis processing stage (300), including a chain (400) for processing the preprocessed digitized signal dedicated to COM emissions and a chain (500) for processing the preprocessed digitized signal dedicated to RAD emissions, the primary analysis processing stage (200) including a discrimination module capable of applying the preprocessed digitized signal at the input of the chain (400) dedicated to COM emissions and/or of the chain (500) dedicated to RAD emissions, from primary characteristics determined for the incident signal.

Abstract: A method for manufacturing a radio-direction-finding antenna array in two dimensions includes a step of designing the antenna array with the help of predetermined constraints, the designing step comprising: a step of defining a reference antenna network, a step of searching for configurations to be taken into consideration of each of the antennas forming a direction-finding antenna array, a step of quantifying the maximum level of ambiguities of each of the possible configurations with the help of a correlation function so as to associate an evaluation quantity with each of the configurations considered, a step of searching for and selecting the configuration exhibiting the lowest evaluation quantity.
