scanning antenna

Since the antenna under test and the probe are stationary and control of the phase of antenna element is only needed, the method is actually an electrical scanning approach substituting the traditional mechanical scanning.

由于使用该方法时要求被测天线和探头均固定不动，仅要求对天线各单元的配相进行控制，故实际上这是用电扫描方法来代替传统的机械扫描方法。

Under the condition of the same number of elements, the aperture of sparse antenna array is larger than uniform antenna array with the same geometric structure. So sparse antenna array has more narrow scanning beam and better spatial resolution.

当阵元数目相同时，稀布阵列比具有相同几何结构的均匀阵列拥有更大的孔径，从而得到更窄的扫描波束，提高了阵列的空间分辨率。

Radar target azimuth information is obtained by the antenna beam scanning, the radar antenna azimuth resolution depends on the horizontal beam width, if it is a narrow beam, you can get high resolution.

雷达目标的方位信息是由天线波束扫描得到的，雷达方位分辨率取决于天线的水平波束宽度，如果是窄波束，就能得到高分辨率。
