本文综述了真时延（TTD）的主题及其在宽带成像相控阵中的重要性和意义。本文介绍了早期的模拟版本的TTD使用“罗特曼透镜”，讨论了各种架构，并谈到光子实现。还强调的是窄带阵列，在个别频率校准和宽带成像阵列TTD是必要的设计之间的差异。
This paper reviews the topic of true time delay (TTD) and its importance and implications in wideband imaging phased arrays. The paper describes an early analog version of TTD using the "Rotman lens," discusses various architectures, and talks about photonic implementations. Also emphasized are the differences in design between narrow-band arrays which are calibrated at individual frequencies and wideband imaging arrays where TTD is necessary.
