Abstract

The invention relates to a two-dimensional rotation top precision detecting method, which relates to the technical field of electromagnetic scattering. The two-dimensional rotation top precision detecting method comprises the steps of: adjusting a pitch angle and an azimuth angle of the two-dimensional rotation top to initial angles, making the two-dimensional rotation top to do azimuth motion ata first angle interval, and acquiring coordinates of a reflector under each theoretical azimuth angle by means of a laser tracker; making the two-dimensional rotation top to do pitching motion at a second angle interval, and acquiring coordinates of the reflector under each theoretical pitch angle by means of the laser tracker; and determining positioning precision of the azimuth motion and the pitching motion as well as an orthogonal degree of an azimuth axis and a pitch axis of the two-dimensional rotation top in a no-load state according to the coordinates of the reflector under each theoretical azimuth angle and the coordinates of the reflector under each theoretical pitch angle. By adopting the steps, the accuracy degree of the positioning precision of the azimuth motion and the pitching motion obtained through detection can be improved, the detection of the orthogonal degree of the azimuth axis and the pitch axis is realized, and the comprehensiveness of precision detection of the two-dimensional dome can be improved.

Description

technical field

[0001] The invention relates to the technical field, in particular to a two-dimensional rotating top precision detection method. Background technique

[0002] Radar cross section (RCS, radar cross section) measurement is an important method to study the electromagnetic scattering characteristics of targets. The compact field RCS measurement system is mainly composed of shielded microwave anechoic chamber, compact field, two-dimensional low-scattering metal support, one-dimensional foam support, signal transceiver and acquisition processing equipment, measurement auxiliary equipment, etc. The two-dimensional low-scattering metal bracket is a kind of support structure, which has a strong load-bearing capacity and can realize the continuous movement of the target in the two-dimensional directions of azimuth and pitch to simulate the attitude angle of the target's motion state.

[0003] The two-dimensional turn top is a structure used to install the target on th...
