本文提出了一种宽带FMCW MIMO雷达传感器，能够工作在120 GHz和140 GHz之间的频率范围。该传感器基于SiGe技术制造的雷达芯片组，并使用MIMO方法来提高角分辨率。MIMO操作通过发射机的时域复用来实现。该雷达能够通过使用FFT处理和延迟求和波束形成器来产生2D图像。本文介绍了整个雷达系统的设计与图像重建算法，以及第一次成像结果。
This paper presents a wideband FMCW MIMO radar sensor capable of working in the frequency range between 120 GHz and 140 GHz. The sensor is based on a radar chipset fabricated in SiGe technology and uses a MIMO approach to improve the angular resolution. The MIMO operation is implemented by time domain multiplexing of the transmitters. The radar is capable of producing 2D images by using FFT processing and a delay-and-sum beamformer. This paper presents the overall radar system design together with the image reconstruction algorithms as well as first imaging results.
