Description

A tilting platform for antenna testing

technical field

The utility model relates to the field of electronic technology, in particular to an antenna testing pitch platform.

Background technique

At present, antenna pattern measurement is an important and complicated work in the antenna research and manufacturing process. In the process of developing high-precision and high-performance radar antennas, it is often necessary to know the gain and sidelobe characteristics of the antenna in all directions in the working airspace. Therefore, it is necessary to measure the antenna's pattern in the entire airspace. The main test method for antenna pattern measurement is the far-field test method. The specific implementation method is to install the antenna on a turntable with azimuth rotation and pitch rotation. When these turntables drive the antenna to rotate a circle along the azimuth plane parallel to the horizontal plane, Then the pattern of the antenna on the azimuth plane can be obtained; when enough elevation angles are selected, it means that more patterns on the corresponding azimuth plane are obtained, and thus the gain of the antenna in the entire airspace can be obtained.

However, in actual operation, due to the fact that these turntables will inevitably cause an offset of the antenna’s up and down angles during the rotation process, these offsets are generally not corrected in the existing test process, which will eventually lead to different antennas in the test. There is a certain error in the direction diagram of the azimuth plane, and as the pitch angle increases, the error will also increase. When the accuracy of the direction diagram is high or when the phase pattern is tested, this error is actually intolerable of. When the measurement results exceed the allowable error range, the measurement results will have a greater impact on the technical performance and actual use efficiency of the antenna.

It can be seen that there are technical problems in the prior art that the platform used for antenna testing cannot guarantee that the pitch of the antenna is always consistent during the testing process, which causes errors in the measurement results and affects the technical performance and actual use efficiency of the antenna.
