Abstract

The invention discloses a probe consistency detection system for a multi-probe spherical near field. The probe consistency detection system comprises a horn, a first rotation mechanism, a second rotation mechanism, a laser aligner, a control device and a balance frame, wherein the second rotation mechanism is disposed on the balance frame and connected with the horn; the first rotation mechanism is disposed on the balance frame; the horn is disposed on one end of the balance frame; the laser aligner is disposed on the other end of the balance frame; the horn, the first rotation mechanism, andthe second rotation mechanism and the laser aligner constitute a weight balance system on the balance frame; the second rotation mechanism is configured to drive the horn to rotate at a constant position; the first rotation mechanism rotates the balance point of the weight balance system around a fulcrum, the position of the balance point of the weight balance system remains unchanged; the controldevice is connected with the first rotation mechanism and the second rotation mechanism for providing control signals for the first rotation mechanism and the second rotation mechanism.

Description

technical field [0001] The present application relates to the technical field of probe consistency, in particular to a probe consistency detection system for multi-probe spherical near-field. Background technique [0002] The probe consistency of the multi-probe spherical near-field is one of the most important indicators for evaluating the near-field measurement site of the base station antenna. At present, the test methods and test instruments are not yet perfect, the main technical methods are controlled by foreign companies, and the algorithms are not disclosed. As a result, the project acceptance and regular measurement and calibration of the base station antenna near-field measurement site need to rely on the original foreign manufacturers, resulting in technical barrier. Contents of the invention [0003] The purpose of the embodiment of this application is to provide a probe consistency detection method for the multi-probe spherical near-field, to break through te...
