In addition, simulation results are given to show the effect of reject the main lobe interference on the sum and difference patterns.

另外，本文给出了为消除主瓣干扰而对和差方向图影响的模拟结果。

There are two disadvantages in adaptive beam forming in the presence of main lobe interference, one is heightening of side-lobe level, the other is distortion and peak offset of main beam.

在自适应波束形成技术抑制干扰问题中，当存在主瓣干扰时，便暴露出两个缺陷：一是副瓣电平增高；
