在毫米波（mmWave）频段采用单输入多输出（SIMO）架构的全数字宽带联合通信雷达（JCR）将实现高联合通信和雷达性能，并增强设计灵活性。带有少量模数转换器（adc）的量化接收器将为未来的便携式设备和自动驾驶汽车提供实用的JCR解决方案，同时降低功耗。在本文中，我们提出了一个名为JCR70的联合通信雷达概念验证平台，通过71-76 GHz频段的真实信道测量来评估和演示这些JCR系统的性能。我们通过使用额外的全双工雷达接收器扩展毫米波通信设置，并使用滑动导轨上的移动天线捕获SIMO JCR信道来开发该平台。为了表征我们开发的测试平台的JCR性能，我们进行了几个室内和室外实验，并对测量数据应用了传统和先进的处理算法。实验结果表明，采用2-4 b ADC的量化接收机在信噪比高达5 dB的情况下，性能与高分辨率ADC相当接近。此外，我们还将JCR70平台的性能与INRAS Radarbook进行了比较，INRAS Radarbook是77 GHz的最先进的汽车雷达评估平台。
A fully-digital wideband joint communication-radar (JCR) with a single-input-multiple-output (SIMO) architecture at the millimeter-wave (mmWave) band will enable high joint communication and radar performance with enhanced design flexibility. A quantized receiver with few-bit analog-to-digital converters (ADCs) will enable a practical JCR solution with reduced power consumption for futuristic portable devices and autonomous vehicles. In this paper, we present a joint communication-radar proof-of-concept platform, named JCR70, to evaluate and demonstrate the performance of these JCR systems using real channel measurements in the 71–76 GHz band. We develop this platform by extending a mmWave communication set-up with an additional full-duplex radar receiver and by capturing the SIMO JCR channel using a moving antenna on a sliding rail. To characterize the JCR performance of our developed testbed, we conduct several indoor and outdoor experiments and apply traditional as well as advanced processing algorithms on the measured data. The experimental results show that the quantized receiver with 2–4 b ADCs generally performs quite close to the high-resolution ADC for a signal-to-noise ratio of up to 5 dB. Additionally, we compare the performance of our JCR70 platform with the INRAS Radarbook, which is a state-of-the-art automotive radar evaluation platform at 77 GHz.
