| Abstract: | This paper deals with the algorithms for forming adaptive nulls of the sum and difference patterns in digital beamforming,and gives an outline of the approach to getting the sum and difference simultaneously.The effects of amplitude and phase errors in the intercoupling and receiving channels on the sidelobe and the adaptive nulling are discussed.A way that eliminates the effects of amplitude and phase errors is presented.It is proved that the weighting and the LMS algorithm can not be interchanged. |
