Visual implementation method and visual implementation device for measuring precision of microwave reflection surface

Abstract

The invention provides a visual implementation method and a visual implementation device for measuring the precision of a microwave reflection surface. In the local point contact manner, the automaticacquisition is carried out and the data points of the reflection surface are collected. The normal numerical points of the reflection surface are recorded. The values of an actual microwave reflection surface and the values of a standard microwave reflection surface are fitted according to longitude and latitude directions, and then a comparison visual result of the standard microwave reflectionsurface and the actually-measured microwave reflection surface is obtained. The above operation mode of the method is local contact, so that the precision of the reflection surface cannot be influenced by the local contact mode. Meanwhile, the defect that the mechanical measurement method cannot be used for measuring the micro projection is overcome. Through the corresponding special calculation process, a corresponding visual result is obtained through the software.

technical field [0001] The invention relates to a microwave antenna measurement technology, in particular to a method and device for visually realizing the precision measurement of a microwave reflection surface. Background technique [0002] As one of the important terminals of the communication system, the microwave antenna is widely used in point-to-point wireless communication. The parabolic antenna is one of the most common implementation methods in the microwave field. The reflective surface is the core component of the parabolic antenna. Performance indicators are good or bad. [0003] In current projects, mechanical measurement is usually used to measure the accuracy of the reflective surface. At present, the curve plate and feeler gauge are often used to measure the normal clearance value L of evenly distributed points. i , and calculate its root mean square However, with this method, there are the following problems: [0004] If mechanical measurement is used, ...

Problems solved by technology

[0004] If mechanical measurement is used, only the normal gap between the curved backing plate and the reflective surface to be measured can be measured, but the tiny protrusions in the normal direction cannot be measured, and the contact between the curved backing plate and the measured reflective surface will affect the accuracy of the opposite surface due to gravity. a certain degree of influence;

[0005] The root mean square value is used to judge the accuracy of the reflective surface. This index is a macro-average value. For the judgment of the accuracy of the reflective surface with local severe deformation, judgment failure may occur;

[0006] This measurement method is inefficient, difficult to image, and intuitively reflects the accuracy of the reflective surface. During the measurement process, many subjective factors of the measurer are involved, and it is difficult to achieve the purpose of objectively evaluating the accuracy of the reflective surface.
