Title:DesignofFPGA-BasedOpticalBeamformingControllerforPhasedArrayAntennas
Abstract:
Phasedarrayantennas,knownfortheirabilitytosteerandmanipulateradiatedbeams,areextensivelyusedinvariousapplications,includingradarsystems,wirelesscommunications,andsatellitecommunicationsystems.Thebeamformingtechniqueiscrucialtoachievethedesiredradiationpatternandmaximizeantennaperformance.Inthispaper,wepresentthedesignofaField-ProgrammableGateArray(FPGA)-basedopticalbeamformingcontrollerforphasedarrayantennas.Theproposedcontrolleroffersadvantagesintermsofflexibility,adaptability,andreal-timesignalprocessingcapabilities,makingitapromisingsolutionfornext-generationphasedarrayantennasystems.
