AI 中文摘要
未来的集成感知与通信（ISAC）网络需要无线平台，这些平台不仅能够适应其信号，还能适应其辐射和观测的物理位置。本文提出了捏合天线系统（PASS）作为ISAC的空间自适应平台。PASS采用介质波导作为信号传输介质，并利用可重构的介质捏合天线，沿波导实现可编程的辐射和观测点。这种独特的架构引入了新的空间自由度，使网络能够动态地重构其与用户、目标及周围环境的交互几何结构，而非仅在固定的天线几何结构上优化信号。利用太赫兹测试平台，我们实验验证了PASS的空间控制和空间选择性接收能力，并展示了两个相干辐射点之间的场构建性合并。我们进一步探讨了这种空间可重构性如何实现无线电图辅助通信、环境分割多址接入和闭环主动无线电感知。最后，我们指出了实现实用PASS-ISAC网络的关键挑战和研究方向。
英文摘要
Future integrated sensing and communication (ISAC) networks require wireless platforms that can adapt not only their signals but also the physical locations from which they radiate and observe. This article presents pinching-antenna systems (PASS) as a spatially adaptive platform for ISAC. PASS adopts dielectric waveguides as signal-transport media and reconfigurable dielectric pinching antennas to realize programmable radiation and observation points along these waveguides. This unique architecture introduces new spatial degrees of freedom, allowing the network to dynamically reconfigure its interaction geometry with users, targets, and the surrounding environment, rather than solely optimizing signals over a fixed antenna geometry. Leveraging a terahertz testbed, we experimentally validate the spatial control and spatially selective reception capabilities of PASS and demonstrate constructive field combining between two coherent radiation points. We further explore how such spatial reconfigurability can enable radio-map-assisted communication, environment division multiple access, and closed-loop active radio perception. Finally, we identify key challenges and research directions toward practical PASS-ISAC networks.
