紧缩场测试扫描架平面度控制系统研制

扫描架是紧缩场现场校准系统的关键测试设备。扫描架扫描平面度是影响校准准确度的关键指标。本文针对自研的扫描区域为φ6m的大型极化扫描架，设计了一套扫描架平面度实时补偿系统。该实时补偿系统可以实时检测扫描架扫描平面相对于基准平面的位置偏差，并通过伺服补偿机构完成补偿。测试结果表明该实时补偿系统可以准确、快速完成平面度的补偿，与半实时补偿方式相比具有更高的效率及精度。目前，该系统已成功应用于紧缩场现场校准。

Development of Control System for Planeness of Compact Range#br# Measurememt Scanner

The measurement scanner is one of the key equipments for measurement system of the compact range.Scan planeness of scanner is one of the key indicators that affect measurement accuracy. In this paper, a real-time compen?sation for planeness of the measurement scanner is designed, for a large polar scanner with a scanning area of φ6m. The real-time compensation system can detect the positional deviation of the scan plane relative to the reference plane in real time and the servo compensation agency completes the compensation. The test results show that the real-time compensation system can accurately and quickly complete the planeness compensation. Compared with the semi-real-time compensation method, it has a higher efficiency and accuracy. Presently, the real-time compensation system has been successfully applied to the calibration of compact range.
