相控阵系统中天线罩高效测试技术的研究

RCS Simulation and Reduction of Electrically-large Radome of FSS

对现有紧缩场测试系统进行了升级改造,综合多项技术,实现了多波位连续测试和多通道瞄准误差测试,首次解决了相控阵系统中天线罩高密度高强度测试的多项关键问题,改造后该天线罩自动测试系统提高了天线罩的测试效率和测试精度。

Using the research result of multiple radome test methods, the existing compact range is upgraded and rebuilt. The continuous measurement of radome's electrical properties at different beam positions is accomplished. And the multiple-channel measurement of bore sight error is also realized. Several key problems in the high-intensity and high-density radome testing work of phased-array system are solved for the first time. Applying this new automated testing system, test efficiency and precision are improved.
