High-precision detachable antenna four-dimensional motion device

Abstract

The invention provides a high-precision detachable antenna four-dimensional motion device comprising a moving platform, a detachable guide rail, an antenna polarization device and an antenna adapting device. The detachable guide rail is perpendicularly installed on the moving platform, the antenna polarization device is perpendicularly installed on the detachable guide rail, the antenna adapting device is installed on the antenna polarization device and moves toward the front, back, left and right directions through the moving platform, the detachable guide rail ascends and descends, the antenna polarization device can move in polarization manner, and thereby the device can realize four-dimensional motion. Forward direction of the moving platform is always kept perpendicular to a target by a parallel range-measuring real-time adjustment travelling method, the high-precision detachable antenna four-dimensional motion device is detachable and convenient to load and transport, and the antenna polarization device can be connected with various antennas by being connected with different antenna adapting devices.

Description

Technical field: [0001] The invention relates to an antenna movement device, specifically a high-precision detachable four-dimensional antenna movement device, which realizes the four-dimensional movement of the antenna in front and back, left and right, up and down, and polarization. It can be adapted to various antennas and can also be disassembled. Easy to box and transport. Background technique: [0002] In the military field and modern warfare, it is very important to reduce the electromagnetic radiation of military electronic equipment. At present, electromagnetic shielding shelters are generally used as the vehicle-mounted operating environment for military electronic equipment. In the design of electromagnetic shielding shelters, the level of shielding effectiveness is a key indicator to measure product performance. At present, most of the measurement methods of shielding effectiveness adopt "GBT12190-2006 Measurement Method of Shielding Effectiveness of Electromagn...

AI Technical Summary

Problems solved by technology

Since there is no corresponding automatic test device in China, manual measurement is adopted

There are three main problems caused by manual measurement: 1) The test time of shielding effectiveness is relatively long, and the whole test process requires the tester to hold the antenna by hand, which is a very heavy workload and consumes a lot of manpower; 2) The shielding effectiveness test is in the electromagnetic radiation In the environment, this will cause great harm to the health of testers who have been engaged in shielding effectiveness testing for a long time; 3) The testing of shielding effectiveness generally requires high test accuracy, and manual measurement cannot guarantee high accuracy, so it is inevitable test error
