Problems solved by technology

In addition, the ultra-large-scale compact field will increase the difficulty and manufacturing cost of the overall positioning of the reflective surface and the feed source, and it will be difficult to deal with the non-uniform settlement of the concrete foundation caused by non-uniform load, which will further cause the feed source to irradiate the reflective surface of the compact field out of focus Quiet zone quality deterioration

Abstract

The invention discloses an antenna-feed compact range device mainly composed of a compact range reflection surface, an adaptive positioning feed source, a laser tracker and a microwave darkroom. The compact range reflection surface is a quadric surface. An increase in the size of the reflection surface causes a quadratic increase in the two-dimensional bending offset of the reflection surface, andthus aggravates structural deformation and long-term creep caused by self-weight, and reduces the structural stability and the profile accuracy of the reflection surface system. According to the antenna-feed compact range device, the reflection surface is a recumbent structure, and the feed source is configured in antenna-feed arrangement, which is beneficial to improving the structural stabilityand the profile accuracy of a super large-scale compact range reflection surface system and the plane wave quality of a compact range dead zone.

Description

technical field [0001] The present invention relates to the technical field of compaction field, in particular to a highly stable antenna feeder type compaction field device, the overall structure adopts antenna feeder layout, the main purpose is to improve the stability of the structural system of the compaction field and reduce the ultra-large-scale compaction field Structural design and manufacturing are difficult, improving the plane wave quality and long-term stability of the quiet zone of ultra-large-scale compact fields, especially suitable for ultra-large compact fields with reflective surfaces exceeding 30m. Background technique [0002] With the large-scale and mass-produced large-scale electronic equipment, such as the installation and maintenance of full-scale aircraft and large-scale ship-borne phased array radar, the demand for precise measurement of full-scale radar target scattering and large-aperture antennas is becoming increasingly urgent. The traditional ...
