摘要
天线罩用于保护天线不受外部环境影响,但同时它会影响天线的精度,所以天线罩电性能的计算、分析、设计和检验已成为该领域的主要研究方向。阐述了天线罩瞄准误差和传输效率的测试理论、方法和系统组成,给出了软件流程和测试结果,实现了实时电轴跟踪,并基于动态电轴跟踪法进行了参数测试。所设计的天线罩瞄准误差和传输效率自动化测试系统达到了较高的自动化测试水平和测量精度。
Radome is used for protecting antenna far away from external environmental inferences, but it brings disadvantage of decreasing the accuracy of antenna. Thus calculation, analysis, design and tests on electric performance of radome have become the main research scope in the area. The theory, method and system composition of testing bore-sight error and transmission efficiency are described, and the software flowchart and test result are given. Based on dynamic axial tracking, the parameters are tested; and real-time axial tracking is implemented. The automatic test system that is proposed meets higher test level and measurement accuracy.
