摘要
通过对尖劈吸波材料的选型和优化设计,建造完成FAST工程综合测试微波暗室。满足国家军用标准(GJB151B)和民用标准电磁兼容测试要求,在500 MHz以上频段满足天线测试环境要求,可为500 m口径球面射电望远镜进行电磁兼容及天线性能测试提供所需的电磁环境和测试条件。通过有效消除外来的电磁波和各种内部反射干扰,以获得可靠规范的测试数据。该综合测试微波暗室可满足国标和相关国际标准的电磁兼容测试及天线测试需求,能实现3 m法和天线性能测试环境保障。
Through the selection and optimization design of the wedge absorbing material, the FAST engineering comprehensive test microwave darkroom is completed. It meets the requirements of （GJB151B） and civil standard electromagnetic compatibility test, and meets the requirements of the antenna test environment in the trequeney band above 500MHz. The electromagnetic environment and test conditions are provided for the electromagnetic compatibility and antenna performance test of the Five-hundred-meter Aperture Spherical radio Telescope （FAST）. Through effective elimination of external electromagnetic wave and various internal reflection interference, to reliable and standardized test data is obtained. The comprehensive test microwave darkroom can meet the requirements of electromagnetic compatibility test and antenna testing of national standard and relevant international standards, and can realize the three meter method and the antenna performance test environment protection.
