摘要： In order to compensate for the displacement of a coherent pulse airborne radar, the latter is provided with means for alternately linearly moving forward and backward the phase centre of its antenna system, at the reception, from one cycle radar to the next.The displacement of the phase centre is carried out by introducing a controllable dissymmetry in the illumination of the linear radiating aperture of the antenna system.

摘要： A multilayer antenna is provided, which includes a power supply portion generating a wave, a radiating portion, and a guide portion that makes it possible to guide the wave from the power supply portion to the radiating portion. The guide portion includes: at least two stacked guide layers having parallel planes and, for each pair of adjacent layers, a transition between the adjacent layers, including a reflector engaging with a slot-coupling. For at least one pair of adjacent layers, for which the guide portion includes a non-planar reflector, the slot-coupling includes a plurality of slots. Each slot includes a main body that is elongate along at least one axis. The slots are placed on at least one row and together form a pattern that extends along the reflector and has a shape that is dependent on the shape of the reflector.

摘要： A rotatable reflector antenna system that supports on-the-move communications to and from a mobile land, airborne, or maritime vehicle with a remote communication device, such as a geostationary satellite. The antenna system can include a pillbox antenna, a line feed antenna, or an array of horn antennas that convey electromagnetic waves between a transceiver (transmitter and/or receiver) and a reflector. The reflector may be embodied as a singly curved, parabolic cylinder reflector coupled to support members in a manner that enables the reflector to rotate with respect to the antenna. The reflector can rotate in a first direction, such as an elevation rotation, and the entire antenna system including the reflector can be mounted to a turntable or other rotatable platform that rotates in a second direction, such as an azimuth rotation.
