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。

After using compatible compression of multiple scan chains to pretreat the merged test set, modified distance-marking method is used to compress test data.

先采用多扫描链相容压缩预处理总测试集，接着使用改进的距离标记法压缩测试数据。

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.
