位于高度定向基站附近的移动终端的高速检测和识别对于未来毫米波通信系统至关重要。我们提出了一种新型光电调频连续波（FMCW）雷达系统，用于检测、定位和识别多个移动终端。通过使用频率扫描毫米波漏波天线（LWA）和后向散射通信来实现多个移动终端的同时定位和识别。 LWA 提供基于 RF 的波束控制，用于使用 FMCW 雷达信号估计回波的到达方向。此外，在移动终端中实施反向散射技术可以识别用户。因此，无需使用任何复杂的雷达信号后处理算法即可同时进行用户定位和识别。最后，引入的调制后向散射反射将目标信号转移到更高频率，从而表现出更低的本底噪声，从而具有更高的信噪比 (SNR)。
High-speed detection and identification of mobile terminals located in the vicinity of highly directive base stations is essential for future mm-wave communication systems. We propose a novel optoelectronic frequency modulated continuous wave (FMCW) radar system for detection, localization and identification of multiple mobile terminals. The simultaneous localization and identification of multiple mobile terminals is achieved by using frequency scanning mm-wave leaky-wave antennas (LWAs) and backscattering communications. LWAs provide RF-based beam steering for estimating the direction of arrival of the echoes using a FMCW radar signal. Additionally, the implementation of backscattering technology in the mobile terminals allows the identification of users. Hence, simultaneous user localization and identification without the use of any complicated radar signal post-processing algorithms is possible. Finally, the introduced modulated backscattering reflection shifts the signals of the targets at higher frequencies, which exhibit lower noise floor and thus have higher signal to noise ratio (SNR).
