摘要
Abstract
Digital beam forming is a beam forming technology using digital method. Traditional robust LCMV wideband beam forming algorithm setting equality constraint in the expected direction of array response would consume the degrees of freedom used to restrain interference and noise too much. This would restrain the output quality of array antenna and debase rejection capacity to interference signal. In order to overcome the weakness of robust LCMV wideband beam forming algo-rithm,this paper proposes a wideband null broadening and constant beam width beam forming method. This method sets ine-quality constraint in the expected direction of array response boosting rejection capacity to interference signal and output SINR quality. Then The SRV constraint is combined to simplify the constraint conditions in the expected direction and get more the degrees of freedom. Meanwhile the null broadening method is used to set linear constraint in the expected direction and broaden the null in the interference direction. Finally,the quality of this method is analyzed and verified in simulation experiment.关键词
