摘　　要：介绍了在条件有限的同一个空间内设计一种两用电波暗室的思路和方法,包括暗室测试区的功能划分、结构设计、在不同位置选取不同高度吸波材料进行敷设、辅助设施设计等。测试结果表明:该暗室屏蔽效能、场均匀性、环境噪声、归一化场地衰减、静区性能等各项指标均满足设计要求,既满足两用测试功能需求,又符合相关标准要求。The article discusses the design of an anechoic chamber with limited height which can provides an environment for both EMC and antenna testing.The reason and methods of the design are introduced in detail,including the functional division of the test zone,building structure design,the choice of different absorbers with different sizes in different positions,affiliated equipments design etc.The testing results show that the SE,FU,noise floor,NSA and the quiet zone performance all meet the specified technical requirements.That is to say,the performances of the anechoic chamber do not only meet the technical requirements of EMC testing environment and antenna far-field measurement but also meet the relevant standard requirements.
