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.

• 提出了一种基于数字波束形成 (DBF)技术进行副瓣对消的新方法。 与传统的天线副瓣对消相比 ,该方法采用的对消函数与副瓣拟合得较好 ,因而对消剩余较小 ,而且无需大量的计算即可自适应地形成零点 ,能很好地抑制从副瓣进入雷达系统的干扰。
