The present invention relates to the field active electronic scanning radar systems. It provides an architecture for active antenna radar based on a functional unit, the elementary radar unit. The elementary radar unit comprises all of the functions required for generating N independent radar channels. In this regard, it comprises a radiating face with N radiating elements and means for independently generating the radar waves emitted by each of the radiating elements and all of the functions for receiving the waves picked up by this radiating element, together with the digitization of the video signal obtained after reception. It also comprises local digital processing means allowing the digital signals coming from the N channels to be jointly processed. The association of M elementary radar units with a general synchronization module and a global digital processing module advantageously allows a truly modular radar system to be formed, whose configuration can be modified, notably according to the revision of the functions assigned to the radar in question.
