摘要
为了满足对机载合成孔径雷达(SAR)天线稳定平台动态性能的高精度测试的目的,采用基于二维PSD的测量系统测试平台。介绍了该测试系统测量雷达天线微小转角的原理、测试系统的结构、PSD器件的基本原理,数据采集及处理系统的硬件和软件实现。解决了PSD器件实验中的关键技术问题。该系统能精确真实地检测天线平台台体和平台控制装置的主要技术指标,特别是角位置伺服回路跟踪精度时间常数等某些动态指标。实现了雷达稳定平台的自动化测试。
For the precise test of the dynamic performance of SAR antenna stabilization platform on plane, the test system basing on Position Sensitive Detector is applied to test the platform.The test theory of the system in testing slightly rotational angle of SAR antenna, the construction of the test system, the principium of PSD, the hardware and software implement of signal detection and processing system are introduced. The critical technique in PSD testing is solved. The system can precisely measure and evaluate the major technical indexes of antenna platform and its control equipment, especially the dynamic indexes, such as angle location servo loop track precision index etc.High performance automatic test for platform is realized
