但由于存在多余副瓣，驱动效率较低。

However, due to the excrescent side lobe, the current drive efficiency is lower.

任意位置稀布阵通常具有较高的副瓣。

Generally, side lobe level of a sparse-array at arbitrary position is high.

天线获得了良好的高增益、低副瓣特性。

The good performance characteristics of high gain and low sidelobe are obtained.

一般而言，旁瓣在副瓣中站的比例量是最大的。

Side lobes are generally the largest among the minor lobes.

但是，研制低副瓣和超低副瓣相控阵是非常困难的。

But it is very difficult to develop low or very low sidelobe phased arrays.
