摘要
该文给出了高性能天线远场测量暗室设计方法:把暗室菲涅尔区吸波材料成波浪渐变布设,从而将暗室菲涅尔区进入静区的镜面反射变成了多区域漫散射,在需要的中心频点使多区域漫散射矢量相消,达到暗室静区的高性能。这种设计思路在某暗室工程中得到了应用,测试结果表明,较常规暗室静区性能可以提高一个层次。
In this paper,the design method of high performance antenna far field measurementanechoic chamber has been given.The absorbing material in Fresnel zone of anechoic chamber is arranged as wave gradient,so that the specular reflection from Fresnel zone into quiet zone is changed into multi-zone diffuse scattering,and the multi-zone diffuse scattering vector is neutralized at the required center frequency point to achieve the high performance of anechoic chamber quiet zone.This design idea has been applied in an anechoic chamber project,and the test results show that the performance of the quiet zone of the anechoic chamber can be improved by one level compared with the conventional anechoic chamber.
