Phase shift data transfer system for phased array antenna apparatuses |
摘要 |
A phase shift data transfer system for phased array antenna apparatuses having a plurality of antenna elements arranged in rows and columns in an X-Y plane. A phase shifter is connected to each of the antenna elements. In order to form a beam radiating in a desired direction, an amount of phase shift is set in each phase shifter as the sum of a first component and a second component specified by an x coordinate and a y coordinate representative of the location of the antenna element to which the phase shifter is connected. A computing means computes a first component for every x coordinate and a second component for every y coordinate. The first component thus computed is transferred to the phase shifters corresponding to the x coordinate specifying the first component. The second component thus computed is transferred to the phase shifters corresponding to the y coordinate specifying the second component. Each phase shifter adds the first and second components thus transferred and sets the sum in the phase shifter.
