Abstract :
The digital beamforming (DBF) technique discussed is based on a two-step adaptive scheme. A main beam is formed by a conventional digital beamforming algorithm. The space positions of M jammers are estimated and then M beams pointing at the directions of M jammers are formed. An adaptive processing of M+1 order is complemented with some adaptive algorithms. A comparison between partial adaptive arrays and two-step adaptive arrays is made
