Abstract
The present invention relates to a kind of antenna pedestal angle of pitch precision measurement apparatus, it is characterized in that: bracing or strutting arrangement is L-type structure, optical theodolite is arranged in L-type structure, and the upper end of optical theodolite is provided with level meter support, and Miniature water level is arranged on level meter support.During measurement, to be arranged on high-precision Miniature water level on transit pitch axis as measuring basis, transit is used as measurement of angle reading device.Measurement mechanism make use of the angle sensitivity of level meter and the high angular resolution of transit, ensure that transit ground measuring accuracy under high spud angle state by installing support works.This angle-measuring equipment and method thereof have obvious technical advantage, can meet wide range and high-precision measurement of angle requirement simultaneously, meet the requirement of radar pitching angle measurement accuracy detection technique completely.
Description
Technical field
The present invention relates to a kind of method of antenna pedestal angle of pitch precision measurement apparatus and instrumentation radar pitching corner, is a kind ofly detect the indispensable pick-up unit of radar pitching angle measurement accuracy and method thereof.
Background technology
Radar pitching angle measurement accuracy detects to be needed to carry out precision measurement to antenna pedestal pitch axis relative rotation, carries out this type of measurement and need use high-precision wide range angle detection device.The measurement of radar antenna base luffing angle requires that pick-up unit measurement range is not less than 90 °, and angle measurement accuracy is not less than 10 ".Conventional angle detection device has the angular displacement sensor such as code-disc, rotary transformer and the angle measuring instrument such as level meter, quadrant.The angle displacement measurement such as code-disc, rotary transformer element is general in radar is used as angle measuring sensor, generally cannot install this type of measuring sensor again and carries out accuracy detection in radar pitching angle measurement accuracy detects because structure interface is limit.Conventional angle measuring instrument has level meter, quadrant etc., and level meter precision can reach 2 " but range is less, quadrant measurement range reaches ± 90 ° but its precision is only 30 ", therefore two kinds of conventional angle measuring instruments all cannot meet radar pitching angle measurement accuracy testing requirement.
Summary of the invention
The technical matters solved
In order to avoid the deficiencies in the prior art part, the present invention proposes a kind of method of antenna pedestal angle of pitch precision measurement apparatus and instrumentation radar pitching corner, to overcome the deficiency that existing angle measuring instrument can not take into account measuring accuracy and measurement range.
