Abstract:
1. A line measurement method, comprising the following steps performed by a line measurement device: respectively obtaining data of relation between a line length and an insertion loss phase radian of a first-loop gauge and a second-loop gauge under a fixed frequency, and data of relation between the line length and a loop attenuation parameter value; defining a first length range according to two length values obtained by searching the data of relation between the line length and the insertion loss phase radian of the first-loop gauge and the second-loop gauge according to the insertion loss phase radian of a measured loop gauge; and defining a second length range according to two length values obtained by searching the data of relation between the line length and the loop attenuation parameter value of the first-loop gauge and the second-loop gauge according to the loop attenuation parameter value of the measured loop gauge; and determining a boundary of the second length range which is close to a midpoint of the first length range, using a line length value corresponding to the boundary close to the midpoint as a measured line length, and using a line diameter corresponding to the line length value as a measured line diameter.
