WIDE-BAND, PHASE SCANNED ANTENNA

摘要

A wide-band, phase scanned antenna for transmitting a chirped pulse RF signal has a greatly reduced bandwidth/scan angle limitation through the use of a time variable phase shifter coupled to the input of each phase scanned sub-array of the antenna. The phase generated by each one of said phase shifters in response to a command signal being initially zero linearly increases for the duration of said chirped pulse RF signal.
