摘要
微波暗室可以屏蔽外界电磁波的干扰,使测量活动不受外界电磁环境的影响,同时能够抑制内部电磁多路径反射干扰,构建一种对来波几乎全部吸收的纯净的电磁测量环境。大多数微波暗室测试功能一般相对单一,仅能够服务于某一至两项测试需求。该文根据功能需求设计并建设了多功能复合型测试暗室,结合实践经验给出了微波暗室的结构和性能设计方法。该微波暗室具备近场、远场、RCS、北斗导航模拟、复杂电磁环境模拟等多项功能,为所在单位各研究团队提供了多种测试条件,并取得了较好的科研和社会服务效果。
The anechoic chamber can shield the interference of external electromagnetic waves,so that the measurement activities are not affected by the external electromagnetic environment,at the same time,it can suppress the internal electromagnetic multipath reflection interference,and construct a pure electromagnetic measurement environment that can absorb almost all to waves.Most anechoic chambers have relatively single test functions and can only serve one or two test requirements.According to the functional requirements,a multifunctional composite test anechoic chamber is designed and constructed in this paper,and the structure and performance design method of anechoic chamber is given based on practical experience.The anechoic chamber is equipped with near-field,far-field,RCS,Beidou navigation simulation,complex electromagnetic environment simulation and other functions.It provides various testing conditions for each research team in the unit,and has achieved good scientific research and social service effects.
