团队有关降低现有半球共形天线高度同时保证其性能的研究成果在IEEE TAP期刊上发表

发布时间:2022-01-05   点击次数:

论文名称为“Height Reduced Concave Sector-Cut Spherical Conformal Phased Array Antenna Based on Distributed Aperture Synthesis”。该文针对现有的半球共形相控阵天线波束覆盖范围大但是其剖面过高导致其使用场景受限的问题,提出了一种全新的低剖面的凹锥型半球共形相控阵天线。通过引入低剖面共形天线阵结构,结合分布式虚拟口径合成机理,使得空间中离散区域单元可在扫描过程合成相对一致的辐射口径,来保障降低剖面后的扫描性能。同时,通过合理设计阵列的剖面高度及单元3dB波束宽度,将遮挡影响降到最低。最终该天线降低了原有半球共形天线43%的剖面情况下,在半球空域波束覆盖范围内实现了与之基本一致的扫描性能。工作主要完成人林宏声、程钰间、吴亚飞、樊勇

Abstract- The conventional spherical conformal phased-array antenna (SPAA) has a wide beam coverage but suffers from a high profile due to its spherical conformal carrier. In this article, a low-profile conformal array antenna is modified from the conventional SPAA, which can be called the concave sector-cut spherical phased-array antenna (CSSPAA). A distributed aperture synthesis is employed to guarantee that the performance of the CSSPAA is close to that of the SPAA after reducing its height as much as possible. The CSSPAA’s height and the element’s half-power beamwidth (HPBW) are properly designed to minimize the blockage influence due to the special topology of the CSSPAA. A prototype CSSPAA with 48 elements is designed as an example, and the height of the CSSPAA is 43% lower than that of the SPAA with the similar performance in the hemispherical beam coverage. Both numerical and experimental results indicate the effectiveness of the developed method.
