Abstract : This paper is concerned with jamming signals that can potentially defeat or partially defeat know adaptive antenna algorithms. The existence of jammers capable of troubling known adaptive arrays motivates us to develop new adaptive signal processing and array processing algorithms two of which are proposed herein. The goals of this paper are three: (a) to examine signal cancellation phenomena in adaptive beamformers, (b)to formulate approaches toward the elimination of adaptive signal cancellation phenomena, and (c) to introduce spatial dither algorithms to combat signal cancellation and break up smart jammer signals at the receiving array.
