摘要

研制并测试了一种双静态e波段(80GHz)电子扫描成像雷达系统。该雷达系统结合了频率扫描天线内的星型阵列来提取方位和仰角信息,同时利用调频CW (FMCW)收发器来提取距离。这种独特的架构为电子扫描系统提供了最先进的瞬时视场和体素刷新率,同时比传统相控阵系统需要更少的射频组件,从而为电子扫描高分辨率成像雷达的批量生产提供了经济高效的手段。

An E-band Electronically Scanned Imaging Radar System
A bi-static E-band (80GHz) electronically scanned imaging radar system has been fabricated and tested. This radar system combines a stare-mode array within a frequency-scanned antenna to extract azimuth and elevation information, while utilizing a frequency modulated CW (FMCW) transceiver to extract range. This unique architecture provides state of the art instantaneous field of view and voxel refresh rates for electronically scanned systems while requiring less RF components than conventional phased array systems, enabling a cost-effective means for volume production of electronically scanned high resolution imaging radar.
