Based on digital beamforming (DBF) system, this paper presents a new side lobe cancellation scheme on the receiving direction of DBF, by which the active jamming can be effectively rejected without reducing signal detection and measurement acccuracy.

- 提出了一種基于數字波束形成 (DBF)技術(shù)進(jìn)行副瓣對消的新方法。 與傳統的天線(xiàn)副瓣對消相比 ,該方法采用的對消函數與副瓣擬合得較好 ,因而對消剩余較小 ,而且無(wú)需大量的計算即可自適應地形成零點(diǎn) ,能很好地抑制從副瓣進(jìn)入雷達系統的干擾。
