The conclusion shows that reasonable selections of the focal distances of the mainreflector may be able to obtain low RCS, keeping the high-gain under the antenna unchanged.
结果表明，在保持增益不变的情况下合理选择主反射面的焦距是能够达到降低雷达散射截面的需要的。

The surface precision is one of the main technique standards for reflector antennas, which influences the electric performance of antennas directly.
天线反射面的表面精度是主要技术性能指标之一，它直接影响着天线的电性能。
