我们展示了一个使用泄漏平行板波导的太赫兹区域二维雷达系统，它可以支持实时目标跟踪。该系统可以在200毫秒内跟踪目标，距离精度为1毫米，角度为1.4度。由于该系统基于宽带激励，可以同时定位多个目标。宽带激励还可以通过检测非视距路径来感应波导没有直接视距路径的物体。(C) 2020年美国光学学会根据OSA开放获取出版协议的条款
We demonstrate a 2D radar system for the THz region using a leaky parallel-plate waveguide, which can support real-time object tracking. The system can track a target within 200 ms with an accuracy of 1 mm in range and 1.4 degrees in angle. Because the system is based on broadband excitation, it can locate multiple objects simultaneously. The broadband excitation also enables sensing of objects for which there is no direct line-of-sight path to the waveguide, via detection of a non-line-of-sight path.
