Intelligent turntable for testing electrical performance of radome

Abstract

The invention discloses an intelligent turntable for testing the electrical performance of a radome. The intelligent turntable consists of a base, a sliding rail, an azimuth rotating shaft, an azimuthturntable, a pitching support arm, a pitching rotating shaft, a pitching ring, an annular motion mechanism, a radome fixator and an antenna supporting rod, wherein the sliding rail is arranged on thebase, the azimuth rotating shaft is matched with the sliding rail, and on the one hand, the azimuth rotating shaft can move along the sliding rail, and on the other hand, the azimuth rotating shaft rotates; the pitching support arm is mounted on the azimuth turntable, and the azimuth turntable can rotate by 360 degrees around the azimuth rotating shaft; the pitching ring is arranged on the pitching support arm and is connected with the pitching rotating shaft arranged on the pitching support arm, and the pitching ring can pitch upwards or downwards around the pitching rotating shaft; the annular motion mechanism is sleeved with the pitching ring, the annular motion mechanism can rotate around the axis of the pitching ring, and the radome fixator is connected to the annular motion mechanism and used for supporting the radome; one end of the antenna supporting rod is supported on the ground platform, and the other end passes through the radome fixator to support the test antenna in theradome.

Description

technical field [0001] The invention belongs to the technical field of radome testing equipment, and relates to an intelligent turntable for radome electrical performance testing. Background technique [0002] When the radome is installed on the turntable for measurement, it is necessary to simulate the movement state of the antenna in the radome through the azimuth movement, pitch movement, rolling along the central axis of the radome, and forward and backward movement of the turntable, and measure the electric current in each state. performance parameters. The traditional radome test turntable is generally a four-axis turntable, which has the functions of azimuth scanning, pitch scanning, rolling and forward and backward movement. [0003] The turntable realizes the upward or downward movement of the radome through the pitch ring. The rolling ring is located inside the pitch ring, which can realize the rotation of the radome around the central axis. The receiving antenna ...

AI Technical Summary

Problems solved by technology

[0004] Using the existing test turntable structure, every time a state is measured, it is necessary to manually mount and unload the radome on a higher platform, which not only presents the danger of high altitude, but also takes time and effort. When the radome is frequently installed and unloaded, labor The strength is extremely high. During the test process, testers need to pay attention to whether a certain test state is completed and the next state has been measured. Therefore, the traditional turntable measurement technology cannot achieve fully automated measurement of radome.

During manual assisted measurement, on the one hand, there are potential safety hazards, and on the other hand, due to the existence of testers’ subjective factors, the test results are inaccurate
