<p>The present invention relates to the field of active electronic scanning radars. It proposes an architecture for radar with active antenna, based on a functional unit, the elementary radar unit. The elementary radar unit embraces all the functions required to generate N independent radar pathways. In this regard it comprises a radiating face with N radiating elements and means for independently generating the radar wave emitted by each of the radiating elements and all the functions for performing reception and waves picked up by this radiating element, as well as digitization of the video signal obtained after reception. It furthermore comprises local digital processing means making it possible to jointly process the digitized signals coming from N pathways. The association of M elementary radar units with a general synchronization module and a global digital processing module advantageously makes it possible to construct a truly modular radar, the configuration of which can evolve, in particular as a function of the evolution of the functions assigned to the radar considered.</p> |
