Abstract：

The　range-angle-dependent　beampattern　of　frequency　diverse　array　(FDA)　makes　it　capable　of　dealing　with　range-dependent　interference,　which　cannot　be　handled　by　conventional　phased　array.　However,　current　publications　pay　more　attention　to　the　dot-shaped　beam　forming,　which　is　not　suitable　for　the　range-dependent　jamming　signal　suppression.　To　address　this　problem,　this　paper　proposes　a　weight　designing　method　to　control　the　nulls　distribution　among　range　bins　in　the　mainbeam.　With　the　additional　degrees　of　freedom　provided　by　FDA,　it　is　possible　to　flexibly　adjust　the　positions　and　notch　widths　of　the　range　nulls.　The　performance　and　effectiveness　of　the　proposed　weighted　FDA　are　validated　with　numerical　simulations.　©　2013　IEEE.
