论文摘要
雷达和通信（R＆C）作为电磁波（EM）波的关键公用事业具有根本形状的人类社会，并触发了现代信息时代。尽管R＆C在历史上一直在分开进步，但近几十年来，它们一直聚集在集成，形成集成的传感和通信（ISAC）系统，从而在下一代无线网络和未来的雷达中产生了新的，高度可取的功能。为了更好地了解ISAC的本质，本文从信号处理（SP）的角度提供了有关R＆C历史发展的系统概述。我们首先将R＆C之间的二元性解释为信号和系统，然后将其基本原则引入。然后，我们详细介绍了它们技术进化的两个主要趋势，即频率和带宽的增加以及天线阵列的扩展。然后，我们展示了交织在一起的R＆C叙事如何演变为ISAC，并讨论所得的SP框架。最后，我们概述了该领域的未来研究方向。
Radar and communications (R&C) as key utilities of electromagnetic (EM) waves have fundamentally shaped human society and triggered the modern information age. Although R&C have been historically progressing separately, in recent decades they have been converging towards integration, forming integrated sensing and communication (ISAC) systems, giving rise to new, highly desirable capabilities in next-generation wireless networks and future radars. To better understand the essence of ISAC, this paper provides a systematic overview on the historical development of R&C from a signal processing (SP) perspective. We first interpret the duality between R&C as signals and systems, followed by an introduction of their fundamental principles. We then elaborate on the two main trends in their technological evolution, namely, the increase of frequencies and bandwidths, and the expansion of antenna arrays. We then show how the intertwined narratives of R&C evolved into ISAC, and discuss the resultant SP framework. Finally, we overview future research directions in this field.
