机载SAR天线稳定平台测试模块

Testing Module for Stabilization Platform of Airborne SAR

文章简述了机载SAR天线稳定平台的结构以及国内第一个针对机载SAR稳定平台的自动化测试系统的结构,设计并实现了专用于该系统的基于PXI总线的测试模块的电路以及计算机端驱动、数据处理等软件,它模拟惯导姿态信号给平台伺服系统,采集平台跟踪误差信号并通过PXI总线传到主机中进行分析、处理和显示;试验证明,该模块能够圆满完成预定功能。

The structure of antenna stabilization platform of airborne SAR and the structure of automatic test system which is the first one in our country for such platform are introduced. And its special test module based on PXI bus is designed. It simulates signals of INS and outputs to servosystem of platform, synchronously acquires tracking errors of platform. And then these data are given to host through PXI bus. These data are analyzed and displayed in host. It has testified that it can fully implement functions on the schedule.
