Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0014] The principle of the template measurement method of the present invention: if the antenna reflector is a reflector that can be rotated and formed, a rotating template can be made. If the antenna reflector is a non-rotating reflector, a three-dimensional combination template can be used to detect the entire reflective surface.
[0015] Let's take the rotating template as an example to illustrate, such as figure 1 As shown, the tangential shape sample 3 of an ideal antenna is made of physical materials, and the shape of the working side of the sample 3 is a sample curve 8 that is equidistant from the theoretical curve 7 of the antenna (it can be divided into axial equidistant and normal equidistant, commonly used The antenna to be tested and adjusted is placed facing the sky and leveled, and then the sample 3 is installed on the antenna to be test...

The invention discloses a method and a device for detecting a sample plate of the antenna primary side precision. The method is characterized in that a tangent plane shaped sample plate is manufactured to act as a measurement datum, an actual gap value of measurement points of a reflecting surface of an antenna is detected by a measuring tool, and then the error of the reflecting surface of the antenna is determined. The device comprises a rotating shaft (1), wherein the rotating shaft (1) is provided with at least one bracket (2), the antenna is arranged upward, and the bracket (2) is positioned on the antenna. The device further comprises at least one a sample plate (3) which is manufactured according to the shape of an tangent plane of the antenna, and the sample plate (3) is fixed on the bracket (2) and inserted in a sample plate base positioning hole at the center of the antenna and can rotate around the shaft. According to the invention, when antenna primary side precision is detected, people only need to manufacture a corresponding sample plate according to the theoretical size of the antenna, then arrange the sample plate and the antenna on the detecting device together, and mass detection can be carried out quickly.
Description
technical field [0001] The invention relates to a method and a device for detecting an antenna main surface accuracy template, and belongs to the technical field of antennas in communication equipment. Background technique [0002] Communication, radar, remote sensing, radio, television, navigation and other radio equipment all rely on radio waves to work, and all need radiation and reception of radio waves. We call a device that radiates or receives radio waves an antenna. There are many forms of antennas, but usually the antenna has a reflective surface, and the accuracy of the reflective surface is an important indicator for evaluating the quality of the antenna. It not only directly affects the aperture efficiency of the antenna, thereby determining the shortest wavelength that the antenna can work, but also affects The main lobe width and side lobe structure of the antenna pattern. By measuring the surface of the antenna, its surface accuracy can be determined, and i...
