机载SAR天线稳定平台自动化测试系统

Automatic Test Equipment for the Antenna Stabilization Platform of Airborne SAR

根据SAR(SynthesisApertureRadar,合成孔径雷达)平台的工作原理和需要测试的关键性能,以PXI虚拟仪器为核心,使用二维电控转台模拟载机角运动,使用激光测量装置测量平台跟踪误差,设计了机载SAR天线稳定平台的新型自动化测试系统.介绍了系统的结构、软件构成及工作原理.

Based on key capabilities we caring for and the principle of antenna stabilization platform of airborne SAR(Synthesis Aperture Radar), the paper give us the consistent, software structure and principle of an ATE(Automatic Test Equipment) system for such platform. The core of this system is a PXI VI(Virtual Instrument). The system uses an electro-controlling motion simulator to simulate the angle-motion of airplane and laser-test device to test the track error of the platform.
