Abstract: Active millimeter-wave beamforming arrays and focal plane array antennas require extensive calibration to compensate for impairments, such as phase and gain variations between elements, as ...

jq takes JSON as input and transforms it according to the filters you supply. Since it’s a command-line tool, you can pipe ...

Abstract: By controlling the amplitude and phase of the array element, the array antenna synthesizes different beam direction and shape, and has the characteristics of strong directivity, low sidelobe ...
