摘要

本文展示了真时延波束导向对雷达系统的好处。回顾了阵列因子的基本原理，并指出了宽带上的波束斜视问题。讨论了实现时延的可用技术，包括射频光子学、MEMS和mmic。最后，给出了基于mmic的延时模块的测量天线方向图数据，显示在2ghz瞬时带宽上缺乏波束斜视。

True time-delay beamsteering for radar

This paper showcases the benefits of true time-delay beamsteering for radar systems. The basics of array factor are reviewed and the problem of beam squint over wide bandwidths is shown. Available technologies to implement time-delay are discussed including RF photonics, MEMS, and MMICs. Finally, measured antenna pattern data from a MMIC-based time-delay module is presented, showing a lack of beam squint across 2 GHz instantaneous bandwidth.
