When phased array radar operates in wideband wide scan condition, the antenna beam is dispersed and thus the distance profile is broadened.

相控阵雷达天线在进行宽带宽角扫描时，天线波束会“色散”，使得到的距离像展宽，从而降低了系统分辨率。

The scanner itself consists of a digital camera with an on-board laser that determines the distance to the object, although it also apparently requires that targets be placed around the scene to properly scan the object -- or person, as the case may be.
