Abstract :
A two-step adaptive beamforming approach is introduced, which forms the desired radiation pattern through linear combination of a family of auxiliary beams after the number and locations of spatial emitters are obtained by spectral estimation. This algorithm has excellent performance in jamming cancellation, stability, and computational complexity
