摘要： A method for calibrating an ESA radar to mitigate degradation of its radiation system. The radiation system includes the distribution manifold, the ESA radiating elements and the radome the ESA may be operating through. Sensing of degradation takes place both locally with a switchable matched load to identify individual ESA element characteristics and globally with target based radar return data. The data generated by this sensing of both local and global characteristics is then used to modify available ESA element complex weighting to produce a desired far-field radiation pattern.

摘要： A two panel radar system is disclosed. The radar system may include a pair of AESA panels respectively positioned on either side of a central axis, wherein a pointing direction of the first AESA panel is offset by a predetermined angle in a clockwise direction with respect to the central axis and a pointing direction of the second AESA panel is offset by the predetermined angle in a counterclockwise direction with respect to the central axis. A controller may be configured for selectively activating at least one of: the first AESA panel for providing a first coverage area in a first direction offset from the central axis, the second AESA panel for providing a second coverage area in a second direction offset from the central axis, or the pair of AESA panels jointly for providing a third coverage area between the first coverage area and the second coverage area.
