According to the different heighterror requirement of the system, a two dimensional and a three dimensional area for command and guide success are defined.
依据指挥引导高度误差的不同要求，分别定义了二维指挥引导成功区和三维指挥引导成功区。

This paper analyzes the relationship between perpendicular baseline and terrain height sensitivity firstly, based on heighterror induced by uncertainty of phase.
After comparing the detecting result and the actual height of metal parts it showed that the detecting error was in the nature figuration error range of one welding seam.
