Abstract: The invention relates to a radar transmission and reception device comprising a movable antenna (1). The invention is particularly useful in aircraft-borne radars making it possible to obtain information on meteorology. The antenna (1) can be move in rotation about two substantially concurrent axes (2, 3). The antenna (1) is intended to transmit and/or to receive an electromagnetic wave. The device furthermore comprises an electronic module (4) linked to the antenna (1) by a waveguide, the electronic module (4) ensuring the processing of the electromagnetic wave received and/or the generation of the electromagnetic wave transmitted. The electronic module (4) is secured to the antenna (1).
