在这封信中，我们报告了初步的实验结果，这些结果为汽车传感中预期的户外非结构化场景的低太赫兹（低THz）雷达成像提供了基础。简要介绍了低太赫兹单成像雷达传感器的要求和技术指标。讨论了工作在150 GHz的调频连续波（FMCW）雷达的成像能力。对比了150 GHz FMCW雷达和参考30 GHz步进频率雷达在道路和越野场景下的实验图像，并分析了它们的性能。
In this letter, we report initial experimental results which provide the foundation for low-terahertz (low-THz) radar imagery for outdoor unstructured scenarios as expected in automotive sensing. The requirements and specifications for a low-THz single imaging radar sensor are briefly outlined. The imaging capabilities of frequency-modulated continuous-wave (FMCW) radar operating at 150 GHz are discussed. A comparison of experimental images of on-road and off-road scenarios made by a 150-GHz FMCW radar and a reference 30-GHz stepped-frequency radar is implemented, and their performance is analyzed.
