The invention belongs to the technical field of
radar antennas, in particular to a real-time adjustment method for a double-reflecting surface antenna shape surface based on the
best fitting. According to the real-time adjustment method for the double-reflecting surface antenna shape surface based on the
best fitting, a
laser measuring device is installed on the back surface of a secondary reflecting surface, and the
surface shape of a main reflecting surface is measured from the position of the secondary reflecting surface. The
pose matching of the secondary reflecting surface is realized while realizing the
surface shape detection of the main reflecting surface, and the real-time adjustment method is applicable to a non-active main reflecting surface antenna and an active main reflectingsurface antenna. On the premise that it is ensured that a measuring
system does not affect the antenna
electrical performance, the real-time adjustment of the antennas during service can be realized,and the formative factor of antenna deformation is not required to be considered. The real-time adjustment method for the double-reflecting surface antenna shape surface based on the
best fitting issuitable for gravity load, steady-state wind load, slowly-changing
temperature load and
processing and installation errors, and is applied to the real-time adjustment of the shape surface of the largedouble-reflecting surface antenna during service.
