Double-supporting one-hanging object supporting rotary table for RCS measurement

Abstract

Provided is a double-supporting one-hanging object supporting rotary table for RCS measurement. The object supporting rotary table is composed of a central tower, a precise numerical control rotary table, a rotating table, a support unit, a counterweight body and a drawing unit. The central tower is mounted in an installing ground pit of the object supporting rotary table, the precise numerical control rotary table is mounted on the central tower, the rotating table is mounted on a rectangular workbench of the precise numerical control rotary table, the numerical control rotary table drives the rotating table to rotate for 360 degrees, the support unit and the counterweight body are mounted under the rotating table symmetrically, and can rotate together with the rotating table, and the drawing unit is mounted on a drawing unit installation platform. Original supporting and hanging points in an object to be measured are utilized, the original structure of the object to be measured needs not to be changed, the object can be lifted to a measuring position safely, reliably and stably, dismounting is convenient, and the efficiency is high; and a support rod is arranged under the object and supports the object, a drawing rope is hung on the object, and key test parts of the object is almost not shielded in the RCS measuring process.

Description

technical field [0001] The invention relates to a two-support and one-lift target support turntable for RCS measurement, which realizes stable erection, high-precision uniform-speed rotation and high-precision pitching motion of the target to be measured, and belongs to the fields of mechanical engineering and microwave engineering. Background technique [0002] With the development of modern communication technology, satellite technology, deep space detection technology, stealth and anti-stealth technology, the requirements for radar cross-section (RCS) measurement of stealth targets are getting higher and higher. RCS measurement is important for stealth design, detection and identification of targets. has important meaning. In the stages of target stealth design and finalization, RCS measurement and diagnosis of the target to be tested or its scaled model are usually carried out by using test sites such as compact field or outdoor far field. [0003] When RCS measurement ...

AI Technical Summary

Problems solved by technology

At present, the commonly used target support methods mainly include foam support (combined with one-dimensional precision turntable) and low-scattering metal support (one-dimensional turn top). Although both foam support and metal support can achieve uniform rotation of the target to be measured, they have common shortcomings It is impossible to adjust the pitch angle of the target to be measured, and it is impossible to simulate the RCS measurement of the pitch attitude of the target to be measured in the real flight state
