摘要

提出了一种具有拱形结构的宽带共形相控阵系统。该系统包括具有扇形截面的共形天线阵列。此外，共形天线罩与天线阵列集成。介绍了系统的结构。天线阵实测带宽超过20%(驻波比< 1.5)。同时，对系统的扫描特性进行了测量和介绍。在±50°扫描范围内，最大旁瓣电平(SLLs)低于-25dB。

A broadband phased array system with cylindrical conformal antenna

A broadband conformal phased array system with a vaulted geometry is presented in this paper. The system includes a conformal antenna array with a sector cross section. Furthermore, a conformal radome is integrated with the antenna array. The structure of the system is described. The measured bandwidth of the antenna array exceeds 20% (VSWR<;1.5). Also, the scan characteristics of the system are measured and presented. The maximum sidelobe levels (SLLs) are lower than -25dB within the scan range of ±50°.
