Abstract
An antenna apparatus for a radar sensor having a plurality of individual antenna devices that interact through interference to generate and/or receive a radar beam at a predetermined angle of transmission and/or reception. The individual antenna devices are provided with a radar signal and are arranged such that a first angle of transmission and/or reception of the radar beam is determined via an analog beam formation and a second angle of transmission and/or reception of the radar beam is determined via a digital beam formation. The antenna apparatus further includes a feed device configured to generate the radar signal. In addition, the radar beam can be electronically pivoted. Also, an aircraft can include the antenna apparatus.
