Problems solved by technology

[0003] This application proposes a Cartesian coordinate scanning frame system and a splicing measurement method, aiming at solving the problem that the scanning frame system for detection in the prior art belongs to measuring equipment, and needs to be dismantled after the performance detection of the quiet zone, resulting in poor compatibility and scalability. Poor, not easy to reuse the problem, especially to solve the general problem of the performance test of the plane scanning frame system in the quiet zone of large and super-large compact fields, so as to improve its adaptability and expandable performance, making it suitable for the detection of large strokes

Abstract

The invention discloses a rectangular coordinate scanning frame system and a splicing measurement method. The rectangular coordinate scanning frame system comprises a scanning frame vertical movementmodule, a scanning frame vertical fixing module, a scanning frame horizontal movement module, a scanning frame linear translation module, an adjusting sizing block, flatness measurement equipment, a level meter and a wave-absorbing material. The rectangular coordinate scanning frame system solves the problems of poor compatibility and expandability and inconvenient repeated utilization of the scanning frame system for detection in the prior art because the scanning frame system belongs to measuring equipment and needs to be dismounted after detecting the performance of a dead zone, solves theproblem of universality of a planar scanning frame system in performance detection of large and ultra-large compact range dead zones, and can adapt to the demand of a larger stroke through an unlimited splicing mode. In addition, the horizontal module at the original position is kept still all the time in the splicing process, so that the flatness of the original position can be continued in the whole splicing process.

Description

technical field [0001] The present application relates to the technical field of detection of electrical properties in a static zone, and in particular to a Cartesian coordinate scanning frame system and a splicing measurement method. Background technique [0002] At present, in the field of testing the electrical performance of the quiet zone, the electrical detection scanning plane is located in the central section of the quiet zone, and the measurement content includes the amplitude, phase distribution and cross polarization of the main polarization field in the quiet zone. Therefore, a scanning frame system is generally required to realize The planar motion of the antenna is detected to make the above measurements. As the size of the quiet zone increases, the size of the required scanning gantry system also increases. In the prior art, the compact field is used as a device that converts the spherical wave emitted by the feed source into a plane wave or a cylindrical wav...
