Abstract

The invention relates to a mixed measurement analysis method for a satellite antenna. The method effectively solves the problems that various measurement devices are used for co-measurement to reduce detection difficulty and improve detection efficiency during a measurement process of the satellite antenna. The method comprises the steps: cubic mirror collimating measurement is carried out by electronic theodolites during antenna installation and detection processes, scanning measurement of an antenna shaped surface is carried out by a laser radar, a space point position is measured by a laser tracker, and thus the measurement of the satellite antenna is jointly completed by the various measurement devices; union calibration algorithm of 'six freedom degree measurement station three-dimensional network' is employed, a conversion relationship between measurement station coordinates and measurement coordinates is utilized, various observed value error equations are directly listed, so as to overcome shortcomings of a traditional algorithm and improve adaptability of the algorithm. The method provided by the invention is simple, is easy to operate, enables an initial value to be fast acquired, has low requirements for precise degree of the initial value, has a few iteration times, is quick in convergence speed, theoretically is an optimal solution, and has strong algorithm adaptability, high measuring efficiency, fast speed and high precision.

Description

technical field [0001] The invention relates to aviation, in particular to a method for satellite antenna hybrid measurement analysis. Background technique [0002] With the rapid development of aerospace and electronic communication technology, the performance requirements of various radar and communication antennas are getting higher and higher. High-performance antenna measurement technology has become a very important factor in the development and production of antennas. The spaceborne antenna has a very high operating frequency, and the wavelength even reaches the millimeter level, which puts forward extremely high technical requirements for the processing of the spaceborne antenna, especially greatly improving the processing accuracy of the antenna surface and the whole satellite installation of the antenna Accuracy requirements. [0003] At present, the method of satellite antenna hybrid measurement and analysis is to integrate three kinds of measurement equipment, s...
