高性能毫米波天线测试场是毫米波系统研制的关键基础设备之一，然而大口径毫米波天线的测量目前却存在难以满足远场条件和系统链路损耗大的技术挑战，传统的直接远场、近场扫描或抛物面紧缩场都难以有效运用，探索毫米波天线测量的新理论和新技术成为天线测量领域亟需发展的重要课题。本项目以申请人提出的全息紧缩场静区重构的宽带调谐理论为基础，以反射式全息紧缩场为研究对象，研究全息重构出多个波束中抑制干扰波束的理论与方法，基于口径辐射的近轴相似性原理采用馈源调谐实现馈源波前与全息条纹的宽带匹配，通过口径条纹编码权重控制和背板调谐实现干扰抑制、静区质量改善和系统效率提升。本项目旨在揭示反射式全息紧缩场的宽带高效工作机理，进而提出通用设计方法，在不改变全息条纹结构的条件下，通过宽带调谐实现性能优良的毫米波静区，从而为未来大口径毫米波系统整机研制的天线测试场建设奠定理论基础，储备高效设计、高精度制造和测试等关键技术。

High-performance antenna measurement range of millimeter wave is one of the key fundamental facilities. While for the large aperture millimeter wave antenna the measurement is challenged by the plane wave condition and the system link loss. The classical measurement facilities of far field, near field scanning and parabolic reflector compact antenna test range cannot be effectively utilized into the large aperture antenna at the millimeter wave band. Therefore, the novel method based on the new operation mechanism needs to be developed urgently in the domain of antenna measurement. Based on the wideband tuning theory of hologram compact range developed by the applicant, the reflection hologram compact range will be researched in this proposal. The multiple beams are reconstructed in the hologram, whose the undesired beams are suppressed and reutilized only by the pattern coding and backplane tuning, such that the desired ones are properly merged to achieve the high efficiency radiation in the wide band as expected. In this proposal method, no additional holograms are required. The wide band operation principle and design methodology developed by the proposal will lay down the basic foundation, effective design, and high precision manufacture and test for the large aperture millimeter wave systems in the future.
