A two-step adaptive beamforming approach in subarray is introduced in this paper. A main beam is formed by conventional digital beamforming algorithm. The space positions of M jammings are estimated and then M beams pointing at the directions of M jammings are formed. An adaptive processing of M+1 order is complemented with an adaptive algorithm. This algorithm has excellent performances in jamming cancellation, stability, and computational complexity.
