Carrier platform for radar antenna testing

Abstract

The present invention discloses a carrier platform for radar antenna testing. The carrier platform comprises an electric carrier vehicle, a carrying platform, leveling support legs, auxiliary support legs, a turntable, a test frame and a wave absorbing plate; the carrying platform is installed at the rear side of the driving cab of the electric carrier vehicle; a leveling controller is installed on the carrier platform; the leveling support legs are installed at the left side and right side of the carrying platform, the auxiliary support legs are installed beside the leveling support legs, and therefore, system stability can be increased; a turntable interface is mounted on the carrying platform; the turntable is connected with the turntable interface through bolts; the test frame is connected with the turntable through bolts; the wave absorbing plate is installed at the rear portion of the carrying platform; and the wave absorbing plate shields the metal exposed portion of the carrying platform to prevent the metal exposed portion from generating echo reflection, and the wave absorbing plate can absorb antenna echoes. The carrier platform of the invention can carry a variety of kinds of radar antenna devices and move stably in a large range, so that multi-angle testing can be carried out. The carrier platform of the invention has the advantages of high stability in radar antenna testing, convenience in movement, automatic leveling function, high universality and simple and convenient use.

Description

technical field [0001] The invention belongs to the field of radio antenna testing, in particular, it relates to a carrying platform for radar antenna testing. Background technique [0002] At present, there are various forms of radar antennas. Most of the radar antennas need to be tested in the microwave anechoic chamber after the production is completed. The antenna test needs to be leveled, and some antennas need to be tested from multiple angles. These actions need to be carried out on the antenna test delivery platform. completed. The structure of the existing antenna test carrying equipment includes a vehicle, outriggers, and a test frame. The vehicle itself has no power equipment and needs external power traction, which is inconvenient to use. The leveling of the vehicle needs to be carried out with the help of external laser range finder and other equipment, which cannot realize automatic or manual leveling by itself, and the existing antenna test vehicle is difficu...

Problems solved by technology

The structure of the existing antenna test carrying equipment includes a vehicle, outriggers, and a test frame. The vehicle itself has no power equipment and needs external power traction, which is inconvenient to use

The leveling of the vehicle needs to be carried out with the help of external laser range finder and other equipment, which cannot realize automatic or manual leveling by itself, and the existing antenna test vehicle is difficult to realize the rotation and pitching of the antenna equipment, which makes it difficult to perform multi-angle testing. For multi-angle testing, it is necessary to move the electric vehicle to the appropriate angle position several times, and then perform the test after re-leveling. The whole process is time-consuming and labor-intensive, and the operation is cumbersome
