摘要:

低剖面、轻量化、高效率多波段多极化共口径波导缝隙相控阵天线是航天航空领域侦察监视雷达系统的研究热点和难点。本文提出了异形波导嵌套/叠加实现波导缝隙天线多极化、多波段共口径的研究思路，研究了异形波导嵌套/叠加实现波导缝隙天线共口径、高效率、低剖面和轻量化技术途径和方法，探索研究了波导缝隙天线研究中“三个匹配”问题，提出了异形波导结构模式匹配、辐射天线口径场匹配和多物理场集成匹配等“三匹配”的技术方向和研究路径，为进一步研究多极化、多波段和共口径波导缝隙相控阵天线奠定了基础。

Abstract:

The overwhelming research on reconnaissance and surveillance radar system in aerospace is highlighted in low profile，light weight，high efficiency，multi band，multi polarization，and common aperture waveguide slot phased array antenna. A new concept is proposed in this study to realize the multi polarization and multi band common aperture of waveguide slot antenna by embedding or stacking the irregular waveguides.The technical approaches and solutions of realizing common aperture，high efficiency，low profile and light weight of waveguide slot antenna by means of embedding or stacking the irregular waveguides are studied.The three matching problems in the research of waveguide slot antenna are explored. The technology and research means of the three matching problems such as structural mode，radiation antenna aperture field and multiple physical field integration are described，which lays the foundation for the coming research on multi polarization，multi band and common aperture waveguide slot phased array antenna.

Key words: waveguide slot antenna multi band multi polarization common aperture phased array antenna
