Support data for "Use of CRT for Velocity Ambiguity Resolution in FMCW COTS mmWave Radars: An Applied Tutorial"

Automotive millimeter wave Frequency Modulated Continuous Wave radars are finding widespread use in various fields. At times, the hardware specifications of commercial-off-the-shelf products prohibit the use of these products for other diverse radar measurements. More often, velocity ambiguity results when an attempt is made to measure the velocity of a high-speed target with a radar that is not designed for that purpose in the first place. Owing to the cost effectiveness of such products, it is desirable for technologists and application experts to find ways to circumvent and resolve such velocity ambiguity. This tutorial study is thus presented as an applied field example in a challenging environment to demonstrate the use of the Chinese Remainder Theorem for resolving velocity ambiguity. The relevant signal processing and real-life data attributes are discussed along with the indication of possible pitfalls and minute but important considerations. Detailed aspects are explained for tuning the radar parameters for a demonstrative case of a high-speed target with a small radar cross section. Significant field data are gathered and the velocity ambiguity is resolved successfully. Such a tutorial study of velocity disambiguation in radars has not been reported in the literature with similar scenarios, operating frequencies and target speeds, therefore, the field dataset is also made available for further research.

汽车毫米波调频连续波雷达在各种领域得到了广泛应用。有时，商用现货产品的硬件规格限制了这些产品在其他多样雷达测量中的应用。更常见的情况是，当试图使用最初并非为此目的设计的雷达测量高速目标的速度时，会出现速度模糊问题。鉴于此类产品的成本效益，技术专家和应用专家寻求规避和解决这种速度模糊问题的方法变得尤为迫切。因此，本教程研究以一个具有挑战性的应用环境中的实际领域案例，展示了如何利用中国剩余定理解决速度模糊问题。文中讨论了相关的信号处理和实际数据属性，并指出了可能出现的陷阱以及细微但重要的考量。对于高速小雷达截面目标的雷达参数调整进行了详细阐述。收集了大量的现场数据，并成功解决了速度模糊问题。在文献中，尚未报道过在类似场景、工作频率和目标速度下进行的雷达速度解模糊教程研究，因此，该领域数据集也被提供出来，以供进一步研究。
